Nearctic Wasps 
of the 


Subfamilies Pepsinae and Ceropalinae 


Introduction 


The family Psammocharidae includes a large number of common 
wasps that provision their nests with spiders. Typical psammochar- 
ids are long-legged insects commonly seen on flowers or running rap- 
idly over the ground or low vegetation, often nervously flipping their 
wings. A large portion of the Nearctic species are black with black 
wings, though various members of the family are marked or colored 
with red, orange, yellow, white, or metallic blue. Technically, the 
psammocharids may be distinguished from all other wasps by a straight 
transverse groove that divides the mesopleuron into upper and lower 
halves (figure 1,5). This groove is always present, and though other 
wasps possess grooves on the mesopleuron, none but the psammo- 
charids have one that is single, straight, and transverse. The species 
included in the present paper are those belonging to the subfamilies 
Pepsinae and Ceropalinae, occurring in America north of México. 

Previous taxonomic work on these species, except for two papers on 
Pepsis by Hurd, is not outstanding and consists largely of the descrip- 
tion of new species. References to all the original descriptions are 
given in the species headings, the significant papers dealing with 
biology are cited in the synonymy of the species concerned, and the 
few revisional papers may be located by referring to a recent cata- 
logue (Townes and Hurd, 1951, U. S. Dep. Agr., Agr. Monogr. No. 2, 
pp. 907-973). In addition to this literature are numerous locality 
records (largely in state lists), some notes on synonymy and taxon- 
omy, and the well known lectotype lists by Cresson (types in the 
Academy of Natural Sciences of Philadelphia) and by Rohwer and 
Gahan (Provancher types). The specimens which form the bases for 
most of this literature have been restudied and re-recorded accord- 
ing to the taxonomy in this paper. No attempt has been made to 
correct the many errors of identification that occur in literature, but if a 
record in literature is not repeated in the summary of the distribu- 
tional and biological data from pin labels on the specimens studied,

Publications of the U. S. National Museum 


The scientific publications of the National Museum include two 
series known, respectively, as Proceedings and Bulletin. 

The Proceedings series, begun in 1878, is intended primarily as a 
medium for the publication of original papers based on the collections 
of the National Museum, that set forth newly acquired facts in biology, 
anthropology, and geology, with descriptions of new forms and re- 
visions of limited groups. Copies of each paper, in pamphlet form, are 
distributed as published to libraries and scientific organizations and to 
specialists and others interested in the different subjects. The dates 
at which these separate papers are published are recorded in the table 
of contents of each of the volumes. 

The series of Bulletins, the first of which was issued in 1875, contains 
separate publications comprising monographs of large zoological 
groups and other general systematic treatises (occasionally in several 
volumes), faunal works, reports of expeditions, catalogs of type speci- 
mens, special collections, and other material of similar nature. The 
majority of the volumes are octavo in size, but a quarto size has been 
adopted in a few instances. In the Bulletin series appear volumes 
under the heading Contributions from the United States National 
Herbarium, in octavo form, published by the National Museum since 
1902, which contain papers relating to the botanical collections of the 
Museum. 

The present work forms No. 209 of the Bulletin series.

Nearctic Wasps 
of the 


Subfamilies Pepsinae and Ceropalinae 


Introduction 


The family Psammocharidae includes a large number of common 
wasps that provision their nests with spiders. Typical psammochar- 
ids are long-legged insects commonly seen on flowers or running rap- 
idly over the ground or low vegetation, often nervously flipping their 
wings. A large portion of the Nearctic species are black with black 
wings, though various members of the family are marked or colored 
with red, orange, yellow, white, or metallic blue. Technically, the 
psammocharids may be distinguished from all other wasps by a straight 
transverse groove that divides the mesopleuron into upper and lower 
halves (figure 1,b). This groove is always present, and though other 
wasps possess grooves on the mesopleuron, none but the psammo- 
charids have one that is single, straight, and transverse. The species 
included in the present paper are those belonging to the subfamilies 
Pepsinae and Ceropalinae, occurring in America north of México. 

Previous taxonomic work on these species, except for two papers on 
Pepsis by Hurd, is not outstanding and consists largely of the descrip- 
tion of new species. References to all the original descriptions are 
given in the species headings, the significant papers dealing with 
biology are cited in the synonymy of the species concerned, and the 
few revisional papers may be located by referring to a recent cata- 
logue (Townes and Hurd, 1951, U. S. Dep. Agr., Agr. Monogr. No. 2, 
pp. 907-973). In addition to this literature are numerous locality 
records (largely in state lists), some notes on synonymy and taxon- 
omy, and the well known lectotype lists by Cresson (types in the 
Academy of Natural Sciences of Philadelphia) and by Rohwer and 
Gahan (Provancher types). The specimens which form the bases for 
most of this literature have been restudied and re-recorded accord- 
ing to the taxonomy in this paper. No attempt has been made to 
correct the many errors of identification that occur in literature, but if a 
record in literature is not repeated in the summary of the distribu- 
tional and biological data from pin labels on the specimens studied,

it may be regarded as incorrect or unverified as far as my own re- 
searches are concerned. 

Between August 1952 and February 1954, while this paper was 
awaiting publication, K. V. Krombein has published five papers con- 
taining brief but interesting habitat notes on a number of pepsines. 
Most of his specimens have been studied and included in my distri- 
butional data, but his habitat notes are more exact and detailed than 
I have listed them. They can be consulted on the following pages: 
1952, Trans. Amer. Ent. Soc., vol. 78, pp. 91-92; 1952, Proc. Ent. 
Soc. Washington, vol. 54, pp. 176-177; 1953, Proc. Ent. Soc. Wash- 
ington, vol. 55, p. 130; 1954, Bull. Brooklyn Ent. Soc., vol. 49, pp. 
3-4; and 1954, Proc. Ent. Soc. Washington, vol. 56, p. 230. 

This paper completes a taxonomic revision of the Nearctic Psammo- 
charidae, other sections of the family having been treated as follows: 
Aporini by Bradley, 1944, Trans. Amer. Ent. Soc., vol. 70, pp. 23-157. 
Psammocharini by Evans, 1950 and 1951, Trans. Amer. Ent. Soc., 
vol. 75, pp. 133-270; vol. 76, pp. 207-361; and vol. 77, pp. 203-340. 
Pepsis by Hurd, 1952, Bull. Amer. Mus. Nat. Hist. vol. 98, pp. 261- 
304. 


The family name 


Pompilidae, rather than Psammocharidae is a name sometimes used 
for this family, but it may not be so used correctly. The generic name 
Pompilus Fabricius 1898, type of the family name Pompilidae, has 
Pompilus viaticus Fabricius as its genotype. Pompilus viaticus is a spe- 
cies of Sphecidae, because of which the generic name Pompilus may be 
used correctly only in the Sphecidae. In regard to the name Psam- 
mocharidae, its type genus is Psammochares Latreille, 1896, with the 
genotype Sphex fusca Linnaeus. fusca is a species of the subfamily 
Psammocharinae in the present family. The generic name Psammo- 
chares is the oldest name in the family and as such may be used as the 
type of the family name. Pate (1946, Trans. Amer. Ent. Soc., vol. 
72, pp. 123-128) has discussed this nomenclatorial situation in detail. 

Older authors have used the name Pompilidae for the family without 
considering its validity, but in 1910 Banks introduced usage of the 
correct name, Psammocharidae, which steadily gained favor until by a 
generation later the majority of the basic literature of the world used 
this name. Certain workers who wished to continue using the name 
Pompilidae, however, appealed to the International Commission on 
Zoological Nomenclature for an arbitrary declaration that Psam- 
mocharidae was incorrect and Pompilidae was correct. The Inter- 
national Commission obliged by issuing in 1945 its Opinion No. 166, 
throwing its influence behind the usage of the name Pompilidae and 
against the name Psammocharidae. This is one of a series of similar 
actions by the International Commission whose purpose has been to 


INTRODUCTION 3 


promote uniformity in zoological nomenclature and to gain additional 
support for itself by appeasing those zoologists wishing arbitrarily to 
maintain certain names in which their convenience and prestige were 
involved, rather than to submit the disposition of the names to im- 
partial rules of procedure. Although a purpose of the International 
Commission was to decrease confusion, it has so often been misin- 
formed on the specific cases and on certain general nomenclatorial 
situations that confusion has instead been multiplied. It is hard to 
see how the influence of these kinds of actions can endure indefinitely, 
and since their influence is considered temporary they are disregarded 
and the name Psammocharidae is here retained. 

In the preparation of this paper the necessary decisions, both zo- 
ological and nomenclatorial, have been dependent on the painstaking 
collection and consideration of the pertinent data so far as they could 
be unearthed and comprehended. This has meant many hours of 
work and many revisions of previous ideas. Most of the revisions 
have been inconvenient to make, and some which pointed up former 
errors have been embarrassing to admit. But, if it were found that in 
some cases pertinent facts had been purposely hidden or arbitrarily 
dismissed from consideration, users of the paper would conclude that 
it lacked trustworthiness. The human researcher never entirely es- 
capes the influences of laziness and prejudice, but having striven at 
much cost for accurate and honest work in the body of the paper, it 
would be inconsistent to knowingly abandon this course by adopting 
the family name Pompilidae. Such considerations, however, do not 
have an equal appeal to all workers, and many are now using the 
name Pompilidae on the authority of the International Commission 
on Zoological Nomenclature.

In the statement of the location of a specimen or a type, the city of 
an institutional collection or the owner’s name in the case of a personal 
collection is used as the reference word. In Raleigh, North Carolina, 
there are two institutional collections, that of the Department of 
Agriculture and that of North Carolina State College. The former is 
indicated by “Raleigh” and the latter by ‘‘State College, Raleigh.” 

The many institutional and personal collections made available for 
study have permitted correlation of the work of many collectors— 
a tedious job; however, it has been of great value in giving a more 
complete idea of the specific distribution and variation, the oppor- 
tunity, at times, to correct initial misinterpretations with the study 
of more material, and a more nearly complete record of the fauna 
than would otherwise have been possible. I was particularly fortu- 
nate in having the cooperation of Doctors H. E. Evans and P. D. 
Hurd, who collected and sent a great many interesting specimens for 
study. Dr. Evans also sent his flower records, notes on the species 
of spiders captured as prey, and other biological notes. Much of 
the material at the U. S. National Museum, on which this study 
was initiated, was collected by Mr. J. C. Bridwell. Mr. George 
Townes paid especial collecting attention to these wasps and sent 
me many important specimens, mostly from Columbia, 8. C. Mr. 
R. R. Dreisbach assisted by sending manuscript copies of his papers 
and by lending manuscript types for study. Opportunity to see 
some of his extensive work on the genitalia of psammocharids, mostly 
still unpublished, saved much time that would otherwise necessarily 
have been spent in exploratory work on these structures. It might 
be added that the brief treatment of them in the present paper does 
not reflect their total taxonomic value, but rather that other struc- 
tures are usually sufficient for an accurate determination, and that 
Mr. Dreisbach is about to publish photomicrographs of the genitalia 
of nearly all the Nearctic species. Spider prey collected with certain 
of the specimens were determined by Doctors H. H. Swift and B. J. 
Kaston. Mr. K. V. Krombein has reviewed the manuscript with 
the eye of an editor as well as of a hymenopterist, and has sent many 
interesting notes and specimens for incorporation. 

All the types in North American collections except the Provancher 
types and those of Pepsis have been studied. Comparisons with and 
notes on the types of Dahlbom at Lund, Sweden, were made for me

INTRODUCTION 5 


by Miss Louise Russell; comparisons with and notes on the types in 
London and Oxford were made by Mr. J. H. H. Yarrow; Dr. H. E. 
Evans sent a copy of his notes on the Provancher types; and Mr. 
K. V. Krombein sent notes on the Provancher types taken in 1953. 
Assistance from these persons and from the curators of institutions 
and museums at Washington, Philadelphia, Cambridge, Ithaca, 
Raleigh, Lawrence, and San Francisco, who made the types under 
their care available for study, has permitted the kind of nomencla- 
torial work that was sorely needed in this group. Their help is 
gratefully acknowledged. 

Many of Banks’ new species were described from a syntype series, 
without designation of an individual type. Often the number of 
specimens involved and sometimes even the sex is not stated. For 
nomenclatorial purposes I have designated a lectotype in the specific 
synonymy wherever one of Banks’ new names was based on more 
than one specimen without designation of the single type. The 
specimen so designated is usually the one of the series labeled “‘type”’ 
by Banks, though heretofore not designated as such in a publication. 

To my wife goes special acknowledgement for the many ways in 
which she assisted with this study, particularly in recording distri- 
butional data and preparing the maps. The maps are intended to 
give a quick comprehension of the known distribution, with a spot 
for each definite locality. Indefinite localities, like a state, or locali- 
ties not in the atlases at hand, could not of course be indicated by 
definite spots and so had to be omitted. They are included, however, 
in the lists of specimens studied. 


Terminology 


The Rohwer and Gahan (1915, Proc. Ent. Soc. Washington, vol. 
18, pp. 20-76) system of wing vein and cell terminology is used. 
This terminology is explained in figure 1,a. The subgenital plate is 
the last visible sternite—the apparent seventh but actual eighth (or 
the morphological ninth) abdominal sternite in the male, and the 
sixth abdominal sternite in the female. The squama, or paramere, 
of the male genitalia is the lateral distal piece, usually the largest, 
most lateral, most projecting, and most conspicuous paired part of 
the external genitalia. 

An ability to distinguish between males and females is presupposed 
in the keys and descriptions. Males have thirteen segments in the 
antenna (or only twelve in Pepsis formosa), seven visible abdominal 
sternites, no sting, and a more slender build. Females have twelve 
segments in the antenna, six visible abdominal sternites, a sting that 
may frequently be seen exserted, a more robust build, and many 
minor differences from the males in proportions and in the vestiture 
and bristles.

‘Taxonomy 


The Psammocharidae belongs in the Vespoidea and, like the rest 
of the Vespoidea, is probably a derivative of some scoliidlike stock. 
Within the family are two main lines of evolution—the pepsine, 
which is included entirely in the subfamily Pepsinae, and the psam- 
mocharine, which is included in the subfamilies Psammocharinae 
and Ceropalinae. Many authors recognize more than the three 
subfamilies just mentioned. I have studied most of the material 
available in the United States, and though this does not include many 
of the critical exotic genera it is enough to convince me that probably 
all of the additional subfamilies recognized by other authors should 
be merged with one of these three. Homenotus and Aporus, often 
segregated in the Homonotinae or Aporinae, definitely belong in the 
Psammocharinae. Jrenangelus and Notocyphus I place in the Cero- 
palinae, and the ““Macromerinae” is considered a tribe of the Pepsinae. 
The separation of Pepsis as a subfamily distinct from other pepsine 
genera seems quite unjustified. The few ‘Claveliinae’” I have seen 
are aberrant Pepsini. Olizon and related genera, often referred to 
the Psammocharidae, belong in the Rhopalosomatidae, as evidenced 
by the articulation between the first and second abdominal segments, 
upcurved sting, winged tarsal segments of some females, and lack of 
a distinct transverse groove on the mesopleuron.

Subfamily PEPSINAE 


The salient subfamily characters are listed in the key to sub- 
families. The sharp transverse groove on the second sternite of all 
females (fig. 1,c) and some males is the easiest recognition mark. 
Some members of the other two subfamilies have a broad, weak, 
transverse impression in this same position which should not be con- 
fused with the sharp groove of the Pepsinae. The lower inner corner 
of the third discoidal cell is without a pocket, the spinelike bristles at 
the apex of the hind tibia are of rather uniform length and not splayed 
(fig. 1,e), and the dorsal edge of the hind tibia is often serrate. 
The first character will distinguish the Pepsinae from most of the 
Psammocharinae, but not from the Ceropalinae. The second 


1 The Psammocharinae are not treated further in this paper. The Nearctic species have been revised 
by Evans and Bradley in the papers referred to on page 2. 


PEPSINAE: TRIBE PEPSINI 9 


character is held in common with a few Psammocharinae as well as 
with the Ceropalinae. The serrate dorsal edge of the hind tibia, 
though a helpful recognition mark is not reliable as a subfamily 
character, being absent in many groups and present in a few of the 
Psammocharinae (e.g., Priochilus). 

In addition to the key characters, it should be mentioned that the 
thorax of the Pepsinae does not have the indefinable oblique and 
streamlined shape so characteristic of the other two subfamilies. 

There are two tribes, distinguishable as indicated in the key. 


Key to the tribes of the subfamily Pepsinae 


1. Cubital vein of forewing present and pigmented to the wing margin (except in 
Priocnessus and in a few species of other genera); first tergite in dorsal view 
with the sides straight or slightly convex, laterally with a crease which marks 
off an epipleurite (fig. 1,c); parapenial lobe of male genitalia not decurved at

Cubital vein of forewing evanescent at the tip, not reaching the wing margin; 
first tergite in dorsal view with the sides usually somewhat concave toward 
the base, laterally usually without a crease marking off an epipleurite 
(in the Western Hemisphere, only Phanagenia has this crease); parapenial 
lobe of male genitalia rather slender, decurved at the apex to form a 
BRA eet tty eee. Stes Goats os. bey BeRomering. (p. 140) 


Tribe Pepsini 


Cubital vein of forewing usually reaching wing margin (pl. 1, 
figs. 1-10); hind tibia usually with an external dorsal serration 
(fig. 1,e); first abdominal tergite broad, not constricted subbasally, 
so that when seen from above the sides are straight or weakly convex; 
suture or fold separating epipleurum of first abdominal segment from 
the tergite always present (fig. 1,c); last tergite of male seldom with 
a dorsal whitish spot; parapenial lobe of male genitalia not decurved 
apically to form a hook. 

This tribe includes some of the largest and showiest species of the 
family (especially in Pepsis and Hemipepsis), some of medium size, 
and some of small size (as in Dipogon, Priocnemis, and Calicurgus). 
Some of the genera are easily distinguished, but a large complex 
including the Nearctic Chirodamus, Priocnemioides, and Cryptocheilus, 
and a number of additional exotic genera (Cyphononyz, Monodontonyz, 
Mygnimia, Paracyphonyx, etc.) presents a confusing array of species 
with types intermediate to almost any generic limits that may be 
selected. In this situation, there are the alternatives of including all 
in one broad genus, embracing many groups of varying size and dis- 
tinctness, or attempting a larger or smaller number of generic separa- 
tions, some of which would be difficult to defend because of inter- 
mediate species. I have chosen the latter course, because it is closer 
to previously published classifications, results in little generic difficulty

in the Nearctic fauna, and is more in line with the narrower generic 
concepts used in the rest of the tribes. A study of a larger portion of 
the world fauna, however, may show a need for some different 


groupings.

in males; brush on inner side of hind tibia broad, without a distinct 
subapical constriction; last segment of tarsi short, with or without 
preapical spinelike bristles beneath, these when present arranged in 
a short irregular pair of rows, often the basal bristles displaced toward, 
or on the midline; tooth on tarsal claws variable. 

The genus Chirodamus appears to be one of the most primitive of 
the family, as evidenced by the lack of specialization in the venation 
and leg bristles, and by the general scolioid habitus. Its distribution 
is of the Marsupial type. The Nearctic species divide into two species 
groups, which together form a genus amply distinct from others in 
our region, but some of the species in the Neotropic and Australian 
regions approach the more primitive members of Priocnemioides and 
other genera of Pepsini, and in these areas a clear generic separation 
is difficult. 

The species show diversity of structural characters to a degree that 
in other parts of the family has called for generic distinctions. One 
can see by the extensive generic synonymy that some authors have 
used these as generic characters in the present group also. While 
recognizing that there are some well marked species groups in the 
complex, I am not convinced that there should be more than one genus 
used. This is another of the generic problems with which the family 
is replete, but recent progress has demonstrated that much of the 
haziness of generic limits is subjective and may be clarified with study. 
It is hoped that Chirodamus will prove to be another such case. The 
critical species are mostly in southern South America and in the 
Australian region, areas in which North American collections are not 
strong. 

Besides the genotype species mentioned in the synonymy, the fol- 
lowing extralimital species should be referred to Chirodamus. Crypto-

not previously been referred to Chirodamus. I have studied their 
types in Cambridge, Anacyphonyx metallica being represented there

Collection dates are from late in May to early in September and 
seem to indicate two generations a season. Males begin to emerge 
in early summer (May 22 at Neel Gap, Ga.; May 28 at Columbia, 
S. C.; June 1 at Glen Echo, Va., and at Cabin John, Md., etce.), re- 
main numerous through June, and appear to be uncommon in the 
first third of July. From July 9 to 25 there are no records of males 
captured, and males after July 25 presumably represent a second 
generation, which disappears late in August. Females appear a little 
later in the season than males and persist into early September. 
Early and late records for females are June 5 at Rabun Bald, Ga.; 
June 12 at Great Falls, Va.; Sept. 2 at 4,600 ft. on Mount Pisgah, 
N. C.; and Sept. 5 at 5,000 to 6,711 ft. on Mount Mitchell, N. C. 
The usual habitat seems to be rich moist woods. 

This is a species of the Allegheny faunal area from New York to 
Georgia. Adults occur from early to late summer.

hairs, its apex truncate. 

Inner orbit with a yellowish stripe; forewing with a fuscous cloud 
in the second and third cubital and second discoidal cells. Otherwise 
colored like the female. 

Frema.e: Forewing 10.5 to 13 mm. long; temple 0.4 as long as the 
eye (about 0.7 as long as the eye in all other Nearctic species of the

wide; propodeum with weak, coarse, transverse wrinkles; larger 
punctures on sternites sparse and indistinct. 

Black. Wings orange, their extreme bases and the apical margin 
of forewing fuscous. 

This species is atypical of the pyrrhomelas group and somewhat 
transitional to the albopilosus group. An undescribed species from 
Zacapt, Michoacan, México (Evans and Berkeley), is a connecting 
link between deceptus and more typical species of the pyrrhomelas 
group. The male and female of deceptus are associated on slender 
evidence and future studies may prove the association incorrect.

Nearly all collection dates fall between July 1 and Sept. 16. Those 
outside this range are: June 27 at Camp Umatilla, Wash.; June 30 
at Flagstaff, Ariz.; Sept. 28 at Clarkston, Wash.; Sept. 29 at Summer- 
land, British Columbia; Sept. 30 at Logan, Utah; Oct. 13 at Pullman, 
Wash.; and Oct. 14 at Council, Idaho. One male was collected on 
the flowers of Cleome serrulata. 

This species occurs from British Columbia to México, but not in the 
typical Rocky Mountain States of Montana, Wyoming, and Colorado. 
Apparently it is commonest in the Canadian Zone and south of Oregon 
is found only at higher altitudes. Adults are on the wing in the 
last half of summer and in early fall.

Large or very large species of average stoutness, the Nearctic 

species with the forewing 13 to 48 mm. long; clypeus rather large, 

often long; maxilla anthophilous; pronotum rather short, its hind 

margin arcuate; apical end of marginal cell separated from costal 

margin of wing, the cell rounded apically (the apex of this cell is 

adjacent to the wing tip and pointed or subtruncate in the other 

Nearctic Pepsinae); second intercubital vein moderately curved or 

sinuate; second recurrent vein reaching the second cubital cell near its 

basal 0.2; cubital vein reaching the wing margin; base of first discoidal 

cell containing a moderately distinct subcircular irregularity in the 

membrane; nervulus beyond the basal vein by about 0.35 its length; 

nervellus ending far beyond the juncture of cubitella with discoidella; 

anal lobe about 0.8 as long as submediella (pl. 1, fig. 2); hind tibia 

with a strong dorsal serration; brush on inner side of hind tibia broad, 

without a subapical constriction; last tarsal segment with two regular 

rows of bristles beneath; tooth on tarsal claws subbasal, pointed. 

Pepsis is restricted to the Western Hemisphere, where it is repre- 

sented by several hundred species in the Neotropics and fourteen 

species in the southern parts of the United States. Many of these 

fourteen are widely distributed south of our border and reach their 


26 U. S. NATIONAL MUSEUM BULLETIN 209 


northern limits in the extreme south of the United States. All are 
large or very large species which provision their nests with mygalo- 
morph spiders (‘‘tarantulas”’). 

Dr. P. D. Hurd has recently published a monograph of the Nearctic 
species of Pepsis. His keys, synonymy, and distributional conclu- 
sions are given in a synoptic adapted fashion here for the sake of a 
complete record of the Nearctic Pepsinae. For more information on 
taxonomy, biology, and bibliography, or for clarification where the 
treatment below proves inadequate, consult Hurd’s monograph (1952, 
Bull. Amer. Mus. Nat. Hist., vol. 98, pp. 261-334) or his earlier 
revision of the California species (1948, Univ. California, Publ. Ent.,

Large or very large species of average stoutness, the Nearctic species 
with the forewing 11 to 27 mm. long; clypeus moderately large; 
pronotum moderately long, its hind margin arcuate; second inter- 
cubital vein somewhat curved; second recurrent vein reaching second 
cubital cell near its apical 0.1; cubital vein reaching the wing margin; 
base of first discoidal cell containing a conspicuous subcircular irregu- 
larity in the membrane; nervulus beyond basal vein by 0.2 to 0.4 its 
length; nervellus ending beyond juncture of cubitella with discoidella; 
anal lobe about 0.9 as long as submediella (pl. 1, fig. 3); hind tibia 
with « dorsal serration or rippled carina; brush on inner side of hind 
tibia rather broad, without a subapical constriction; last tarsal segment 


PEPSINAE: TRIBE PEPSINI 5 


with two regular rows of bristles beneath; tarsal claws ordinarily with 
two to four erect acute teeth beneath, the basal ones often difficult to 
observe (the claws are reported as “‘bifid”’ in the Ethiopian Hemipepsis 
commixta); empodium large, about 0.75 as wide as apical width of 
last tarsal segment, with a regular apical fringe of about 14 to 40 
setae (in all other Pepsinae the empodium is slender, about 0.5 as 
wide as apical width of last tarsal segment, and with a sparser, less 
regular fringe of about 8 setae). 

This genus includes many large, strikingly colored species of the 
Old World Tropics. In the New World it is replaced largely by the 
genus Pepsis and is represented there by only a few species in Central 
America and México, of which three reach the southwestern United 
States. Some of the names indicated in the generic synonymy are 
used for subgenera by Arnold (1932, p. 291) and by Banks (1934, 
loc. cit.). I have not tried to test their conclusions on the use of 
subgenera, and for the present refer all of our Nearctic species to a 
Hemipepsis without subgeneric divisions.

Forewing of male 15 to 25 mm. long, of female 17 to 27 mm. long. 
Blackish color at wing bases conspicuous, extending on the wing bases 
more than half the length of the anal lobe. 

Banks proposed the name cressoni for this form because Dahlbom 
described his ustulata from “México” and mentioned a bluish colora- 
tion. The female of the present form does have some bluish irides- 
cence, and it must be remembered that in 1842 much of what is now 
in the southwestern United States belonged to México. Miss Louise 
Russell has compared specimens from Texas with Dahlbom’s type for 
me, and reports that they agree very well.

Collection dates range from Apr. 1 at Douglas, Ariz., to Dec. 26 
in Sabino Canyon, Santa Catalina Mits., Ariz. Relatively few of the 
collection dates fall after Oct. 5, and no males are on record after 
Oct. 14. Flower records comprise Polytaenia nuttallii and Daucus 
carota. 

This is a conspicuous form in the southwestern United States 
(except California) and adjacent México, occurring abundantly in the 
Lower and Upper Sonoran faunal areas and commonly in the Transi- 
tion. J have seen it in numbers in April in the Sonoran desert of

Stal’s description of his ochroptera is meager, but agrees with the 
present form perfectly and there are no other species of the genus in 
California. The possibility that he may have had a Cryptocheilus 
instead of a Hemipepsis has been considered but seems remote in 
view of the fact that the two other species of Hemipepsis that Stal 
described at the same time (the Ethiopian iodoptera and ochropus) 
are known to have been correctly placed. 

Specimens (587, 662): From California (Antioch, Benicia, Ben- 
ton Station in Modoc County, Berkeley, Brentwood, Byron, Camp 
Baldy in Los Angeles County, Coalinga, Colton, Concord, Davis, 
Escondido, Hastings Reserve in Monterey County, Humboldt County, 
Jamesburg, Menlo Park, Middleton, Mill Valley, Morgan Hill, 
Mountain View, Niles, Palm Desert in Riverside County, Redwood 
City, San Diego County, San Joaquin Experimental Range in Madera 
County, San Jose, San Rafael, Santa Paula, Sonoma County, Stan- 
ford University, and Telsa); and Nevada (Buffalo Valley in Lander 
County). Also, there are a few specimens somewhat intermediate 
to the subspecies ustulata from Arizona (Pima County and Springer- 
ville) and Nevada (Mesquite, Pyramid, and Reno). 

Dates of collection are from Apr. 15 at Berkeley, Calif., to October 
at Mountain View, Calif. Most of them fall in the summer months. 

This subspecies appears to be common in the Upper and Lower 
Sonoran faunas of middle and southern California. Specimens from 
southern California (San Diego, etc.) are somewhat intermediate to 
the subspecies ustulata, and additional more or less intermediate 
forms are on hand from Nevada, Utah, and northern Arizona. The 
Utah intermediates and most of those from northern Arizona are 
recorded under ustulata ustulata, as they seem to fit best there.

Genus Priocnessus Banks 


Priocnessus Banks, 1925. Bull. Mus. Comp. Zool., vol. 47, p. 337. Type: Salius 
neotropicalis Cameron; designated by Pate, 1946. 

Cressochilus Banks, 1941. Canadian Ent., vol. 73, pp. 119, 120. Type: Pompilus 
nuperus Cresson; original designation. 

Amerocnemis Banks, 1945. Bol. Ent. Venezolana, vol. 4, p. 93. Type: Ameroc- 
nemis bequaerti Banks; original designation. 

Medium sized to moderately large species, of rather slender build, 
the forewing in Nearctic species 6.5 to 17 mm. long; clypeus very 
large, convex, in some males with a highly modified shape; pronotum 
short, its hind margin arcuate; second intercubital vein somewhat 
curved; second recurrent vein reaching second cubital cell at or just 
beyond its middle; cubital vein fading out before reaching the wing 
margin; base of first discoidal cell with a faint subcircular irregularity 
in its membrane; nervulus beyond the basal vein by 0.3 to 1.2 its 
length; nervellus ending at or beyond juncture of cubitella with 
discoidella; anal lobe about 0.7 to 0.8 as long as submediella (pl. 1, 
fig. 4); hind tibia with a strong dorsal serration; brush on inner side 
of hind tibia of moderate width, without a subapical constriction; 
last tarsal segment without or with a few preapical bristles beneath; 
tooth on tarsal claw of female erect and acute, that on tarsal claw 
of male usually more or less modified, sometimes in the form of a 
subbasal lobe. 

Priocnessus is a typical case of a Neotropic genus with intrusions 
into the southern portions of the Nearctic region. No species are 
known from the Eastern Hemisphere. The described Neotropic 
species known to me are Pompilus (Priocnemis) cincticornis Cresson 
1867, Salius (Priocnemis) neotropicalis Cameron 1891, Priocnemella 
monticola Banks 1938, Priocnessus prominens Banks 1945, Ameroc- 
nemis bequaertt Banks 1945, and Priophanes ornata Banks 1945. The 
last species has not previously been referred to Priocnessus. The 
genus is much larger in the Neotropics than this small number of 
described species might indicate. There are six Nearctic species.

Mate: Forewing 6.5 to 9.5 mm. long; clypeus rather weakly convex, 
its apical margin with a weak median tooth, its lateral margin with an 
impressed flange that is widest apically; flagellar segments without 
a longitudinal groove; middle and hind coxae not unusually enlarged; 
hind trochanter without an apical tubercle; subgenital plate tongue- 
shaped, its median longitudinal raised area a narrow ridge which is

evanescent apically and somewhat higher, broadened, and flat-topped 
basally. 

Black. Part of mandible, clypeus except for a median spot reaching 
its apex, face except at the middle, lower lateral part of frons, narrow 
hind orbit, front of front coxa, usually the knees narrowly, outside 
of front tibia, tibial spurs, usually most of first three tarsal segments 
except at their bases and apices, and most of seventh tergite, white; 
tegula brown; wings hyaline, their apices infuscate, the forewing with 
a more or less distinct, short postdiscal fascia centering just beyond 
the apex of the stigma. 

A distinetive color variant has the black of the femora and tibiae 
replaced by fulvous, and often the black of the coxae (especially of 
the front coxa) stained or replaced by fulvous. The type of Prioc- 
nemis leibyt belongs to this variety. A female of corresponding color 
has not yet been collected.{#Another color variation, this one forming 
a geographic cline, involves the wing color. Male specimens from 
Florida have the wings, especially the apical half of the forewing, 
strongly infuscate. This Floridian tendency toward wing darkening 
is present in a diminishing degree in Lower Austral localities increas- 
ingly distant from Florida, being still evident in the Lower Austral 
Zone of North Carolina. 

Frmaue: Forewing 9.5 to 14 mm. long; bind tibia with its dorsal 
teeth rather weak and the bristles in its dorsolateral row about 0.55 
as long as the distance between their sockets; last segment of tarsi 
without preapical bristles beneath. 

Black. Flagellum black; front orbit usually with narrow fulvous 
stain; wings blackish, the forewing with faintly darkened cross-bands 
at the apex, just beyond the apex of the stigma, and along the basal 
vein and nervulus; hind wing a little paler than the fore wing, darkened 
apically. 

Females from the Lower Austral Zone tend to have the wings a little 
darker than females from the Upper Austral and Transition Zones.

Great Falls, Va.; Sept. 13 at Cabin John, Md.; Sept. 19 at Pelham, 
N. H.; and Oct. 1 at Manhattan, Kans. Both sexes have been taken 
at honeydew and there are three prey records—a female taken at 
Washington, D. C., July 10, 1947, by Richard Boettcher, transporting 
an immature Agelenopsis; a female taken at Overbrook, Pa., July 19, 
1914, by G. M. Greene, transporting an Agelenopsis naevia; and a 
female taken at Manhattan, Kans., Aug. 28, 1949, by H. E. Evans, 
transporting a female Agelenopsis pennsylvanica. 

The above records all apply to the typical color form. Males with 
fulvous legs (variety leibyi) have been taken as follows: 207, Atlanta,

o', Morris, Tex., May 22, 1937 (Krombein). It should be noted that 
all of these males were collected earlier in the season than is normal for 
the typical form. With the five males from Wallace, N. C., three 
males of the typical form were collected on the same day and in the 
same habitat. 

This species occurs in Ontario and in most of the eastern half of the 
United States. The normal flight range is about July 1 to Sept. 10, 
but it is on the wing commonly in May, and in Florida in April.

strongly raised upward and outward, its apical margin with a median 
apical tooth; posterior side of median flagellar seements with a longi- 
tudinal groove, within which is a longitudinal row of enlarged special- 
ized setae; middle and hind coxae unusually large; hind trochanter 
beneath with an apical tubercle like a blunt spine; subgenital plate 
tongue-shaped, its median longitudinal ridge high, broad, flat-topped, 
abruptly evanescent beyond the apical 0.75 of the subgenital plate. 





Figure 19.—Localities for Priocnessus nuperus. 


Rufous. Most of mandible, lateral third of clypeus, face, lower 
corners of frons, broad hind orbits, knees, tibiae, and first to fourth 
tarsal segments, orange or bright fulvous; flagellum brown, orange on 
the central third and on the underside of the basal third; ocellar area, 
a small mark above the antennal socket, under side of thorax, region 
of plural sutures, back side of front and middle coxae, most of hind 
coxa, upper side of middle and hind trochanters, and base of first 
tergite, blackish, the extent of the blackish markings variable; wings

teeth very strong and erect, and the bristles in its dorsolateral row 
long, about 0.8 as long as the distance between their sockets; last seg- 
ment of tarsi with about 3 to 8 preapical bristles beneath. 

Rufous. Flagellum with the second, third, and adjacent ends of the 
first and fourth segments yellowish; flagellum beyond the basal 0.3 
of fourth segment blackish; ocellar area, much of back side of head, 
thorax except for top of pronotum, mesoscutum, scutellum, postscu-

tellum, and often area on mesopleuron and propodeum, most of 
coxae, and base of first abdominal segment, black; tegula rufous; 
wings dark brown. 

The species nuperus belongs to a species group separate from the 
Nearctic nebulosus, dakota, coloradensis, and apache, as evidenced by 
the specialized male clypeus, flagellum, coxae, and subgenital plate 
and in the female by possession of preapical bristles on the fifth tarsal 
segment. The Nearctic nigricans belongs probably in the nuperus 
species group but without its male this cannot be concluded with 
certainty. 

SPECIMENS (20 o’, 219): From District of Columbia; Georgia (At- 
lanta); Kansas (Riley County); Maryland (Glen Echo and Takoma 
Park); New Jersey (Gloucester County, Moorestown, and Riverton) ; 
New York (Farmingdale); North Carolina (Hamrick); Pennsylvania 
(Germantown, Ogontz School, and Philadelphia); Texas (Brownsville 
and Lee County); and Virginia (Arlington, Black Pond in Fairfax 
County, Dunn Loring, and Great Falls). 

Dates of collection are mostly from July 2 to Sept. 5. Those 
outside of this range are: Jan. 20 and Mar. 23 at Brownsville, Tex.; 
Oct. 18 in Riley County, Kans.; and October in Lee County, Tex. 
The usual habitat is along the edges of mesophytic deciduous woods 
bordering on overgrown fields. There is one record of a female taken 
at Liriodendron honeydew. 

This species occurs in the Carolinian and Austroriparian faunal 
areas. Except in Texas and Kansas, adults have been taken only 
from July to September, with a few stragglers into October.

Medium or large sized species of average stoutness, the Nearctic 
species with forewing 9 to 26 mm. long; clypeus rather large, convex; 
pronotum of moderate length, its hind margin arcuate; carina on 
mesosternum in front of each middle coxa distinctly angulate medially, 
at the angulation usually produced into a distinct tooth (In all other 
Nearctic Pepsini this carina is evenly curved and without a toothlike 
projection.); second intercubital vein straight, oblique; second re- 
current vein joining the second cubital cell near its apical 0.75; cubital

vein reaching the wing margin; base of first discoidal cell without a 
distinct irregularity in the membrane; nervulus beyond basal vein 
by about 0.2 to 0.7 its length; nervellus ending at, beyond, or some- 
times just before juncture of cubitella with discoidella; anal lobe about 
0.75 as long as submediella (pl. 1, fig. 5); dorsal edge of hind tibia of

MAGNUS GROUP 


Mesosternum with a weak triangular projection on the ridge in front 
of each middle coxa; nipples on posterior part of apical margin of fore 
coxa very weak; brush on inner side of hind tibia not interrupted 
subapically in either sex, slightly to strongly narrowed subapically; 
second sternite of female with a pair of large, weak, cushionlike swell- 
ings but without tubercles; sixth sternite of male gently concave, with 
stiff erect hairs on each side; subgenital plate of male gently concave, 
mediobasally with a faint longitudinal raised area, its apex broadly 
rounded, and its apical and lateral margins with sparse long, and 
dense short upright hairs. 

This species group includes the Nearctic magnus, araius, austrinus, 
and texanus. With its weak tubercles on the fore coxa and weakly 
modified second sternite of the female it is a connecting link with the 
genus Cryptocheilus. The species aratus is somewhat intermediate to 
the fulvicornis group.

Forewing of male 19 to 20 mm. long, of female 20 to 26 mm. long; 
clypeus of male about 2.1 as wide as long, of female about 2.4 as wide 
as long; temple receding from just behind the eye, so that the head 
as seen from above is distinctly narrower across the temples than

across the eyes; propodeum and upper part of metapleuron with sharp 
transverse wrinkles, the wrinkles sharpest in the female; erect hairs on 
head and thorax longer and more conspicuous than in the other species 
of the magnus group; nipples on posterior part of apical margin of fore 
coxa a little stronger than in the other species of the magnus group; 
legs more slender and with longer bristles than in other species of the 
magnus group, the hind femur about 5.4 as long as wide; hind tibia of 
male subcarinate dorsally, without distinct teeth; hind tibia of female 
with a dorsal row of strong, rather narrow teeth that are about 0.8 as 
wide as the length of the bristles beneath each; sixth sternite of male 
basally and laterally with long erect black hairs, discally with sparser, 
shorter, less conspicuous erect hairs; subgenital plate of male with 
marginal irregular long hairs, discally with moderately long hairs 
which in this species are mostly reflexed. 

Black. Wings orange, their apices and extreme bases rather 
abruptly infuscate; head and thorax with an iridescence that is 
usually greenish blue, especially strong in the female.

Southwest, and has been taken also in southern Idaho. Adults occur 
mostly from July to September. 


2. Priocnemioides austrinus (Banks), new combination 


Forewing of male 15 to 21 mm. long, of female 18 to 22 mm. long; 
propodeum and upper part of metapleuron partially or almost 
completely covered with weak transverse wrinkles, these always 
definite in the female but often obsolescent in the male; hind tibia of 
male subcarinate dorsally, with a rudimentary series of teeth; hind 
tibia of female with a dorsal row of strong, rather narrow teeth that 
are about 0.8 as wide as the length of the bristle beneath each; sixth 
sternite of male with erect brown hairs, longer laterally than discally, 
without the contrast in length and density between the sides and the 
disc that obtains in other species of the magnus group; subgenital plate 
of male with a marginal brush of longer hairs, these hairs hardly longer 
on the apicolateral margin than on the apical margin; discal hairs on 
male subgenital plate short, declinate. Structure otherwise as de- 
scribed for P. teranus. 

Black. Wings orange with the base and apex infuscate, to entirely 
black, according to the subspecies; head and thorax with a faint

This is a common species of the Austroriparian and Carolinian 
faunas. There is an isolated record from New Mexico (207, Magda- 
lena Mts., N. Mex., July 1894, F. H. Snow (Lawrence)). Adults are 
on the wing mostly in July and August. 


6. Priocnemioides angusticeps, new species 
PLATE 2, FIGURE 17 


Forewing of male 11 to 15 mm. long, of female 14 to 18 mm. long; 
temple rather sloping, the head somewhat narrower across the temples 
than across the eyes; pronotum of male a little longer than in P. ful- 
vicornis or P. unifasciatus; suberect hair on upper part of pronotum 
moderately long; propodeum with rather fine transverse wrinkling, 
most distinct in the female; subgenital plate of male with a low, weak, 
median longitudinal ridge that tapers from the base. 





Figure 27.—Localities for Priocnemioides angusticeps. 


Black. Flagellum orange; wings orange, infuscate basally and 
apically. In the forewing the basal infuscate area extends about 
0.4 the distance to the basal vein and the apical infuscation just reaches 
or invades the apex of the radial cell. 

This species is superficially similar to P. unifasciatus cressoni but 
may be distinguished by the tapering shape of the median longitudinal 
raised area on the male subgenital plate, the narrower temple, and the 
broader apical infuscation on the forewing.

side of this range are: April at Edinburgh, Tex.; May at Brownsville, 
Tex.; May 17 at Burnet, Tex.; Oct. 4 at Camp Barkley, Taylor 
County, Tex.; Oct. 15 in Brazos County, Tex.; and Dec. 10 at Los 
Mochis, Sinaloa, México. Flower records include only Euphorbia 
marginata. 

This species is known only from Texas and México. Adults are on 
the wing through most of the growing season. 


7. Priocnemioides unifasciatus (Say) 


Forewing of male 9 to 17 mm. long, of female 10 to 21 mm. long; 
temple rather swollen, so that the head across the temples is as wide 
or a little wider than across the eyes; suberect hair on upper part of 
pronotum moderately long; propodeum with rather fine but sharp 
transverse wrinkling, most distinct in the female; seventh sternite of 
male with a median longitudinal raised spatulate area. 

Black. Flagellum fulvous; wings varying from orange with the 
base and apex infuscate to entirely black, according to the subspecies. 

This species ranges from the United States to Patagonia, but is 
represented in that area by a number of subspecies which because of 
their evident color differences have been considered species. They 
are structurally similar but with gradual geographic variation in some 
of the characters which reach distinctive extremes at the ends of the 
range. ‘The structural differences between the subspecies, all minor, 
are in the width of the head across the temples (widest in the Chilean 
subspecies, thence gradually narrowing to the Nearctic subspecies 
unifasciatus), the prominence of the raised spatulate area on the 
male seventh sternite (most prominent in the Chilean subspecies, 
thence gradually less prominent to the Nearctic subspecies uni- 
fasciatus) and size (averaging smallest in the Chilean and Argentinean 
subspecies and largest in the North American forms). In addition, 
the Chilean subspecies has the flagellar segments somewhat shorter 
than in the others. The color differences are described below, where 
all the subspecies are treated, though only three of them are Nearctic.

the fuscous apical portion does not reach or just reaches the apex of 
the radial cell. 

This subspecies is superficially similar to and often confused with 
the species P. angusticeps (see p. 60 for distinguishing notes). It 
has also been confused needlessly with the West Indian P. flammi-

This subspecies bears about the same color and geographic relation 
to Priocnemioides unifasciatus cressoni as does Hemipepsis ustulata 
ochroptera to H. ustulata ustulata. It is of interest to note that the 
subspecies californicus extends into Baja California and intergrades 
with cressoni probably near the California~Arizona boundary, while 
the subspecies ochroptera does not reach Baja California and inter- 
grades with its more eastern counterpart (subspecies ustulata) in 
southern California.

subspecies has been taken at Blythe, Calif., on May 7 and Oct. 3 and 
at Telsa, Calif. on Oct. 15. Two collections were made on the flowers 
of Asclepias. 

This subspecies occurs in central and southern California and in 
Baja California. Most adults are on the wing from early June to 
late September.

distinctly infuscate basally and apically. The basal and apical 
infuscation is not as sharply defined as in the subspecies uricha, 
cressoni, and californicus. Specimens of the present subspecies from 
Argentina in general have less brownish suffusion on the wings than 
do those from elsewhere. 





PEPSINAE: TRIBE PEPSINI 67 


Banks (1946) identifies this form as bonariensis Lepeletier, which 
was described originally in Pepsis. While Lepeletier’s specific 
description agrees, his generic description of the venation of Pepsis 
does not. An examination of his type may show, however, that this 
is the form he had. 

SPECIMENS (70, 159): From Argentina (Bolivar, Carcaraifia,

Black. Pubescence of face and clypeus medium brown; flagellum 
orange; wings black with a slightly brownish tint. 

This subspecies has a strong superficial resemblance to the Nearctic 
P. fulvicornis. It may be distinguished by the longer hair on the upper 
part of the pronotum and by the more distinct wrinkles on the pro- 
podeum, in addition to the specific differences described in the key.

orange; wings orange with the apical margin and the base for a very 
short distance (equal to about 1.5 the length of the tegula) fuscous. 

Spinola mentioned having specimens from Brazil and from Co-

Medium sized species, or sometimes rather large, of average stout- 
ness, the Nearctic species with forewing 6 to 14 mm. long; clypeus 
medium or rather large, convex; pronotum moderately long, its hind 
margin arcuate or somewhat angled at the middle; second inter- 
cubital vein straight or somewhat curved; second recurrent vein 
reaching the second cubital cell near or somewhat beyond its middle; 
cubital vein reaching wing margin; base of first discoidal cell without 
a distinct irregularity in the membrane; nervulus beyond basal vein 
by about 0.25 to 0.5 its length; nervellus ending basad of juncture of 
cubitella with discoidella; anal lobe about 0.65 as long as submediella 
(pl. 1, fig. 6); hind tibia with a dorsal serration, weaker in the male; 
brush on inner side of hind tibia in the Nearctic species rather narrow 
and with a subapical interruption; under side of hind tarsus of male 
with a close fringe of hairs extending from its base to beyond the middle 
(this fringe is absent in all other Nearctic Pepsinae except Priocne- 
mioides.); last tarsal segment with two regular rows of bristles beneath; 
tooth on tarsal claws erect, acute. 

The Nearctic species of Cryptocheilus are all closely related. In 
the Old World the genus is very much larger and with a structural 
diversity that poses problems in generic distinctions from other 
complexes of species. The males of certain Old World species have 
the thorax, especially the pronotum, elongate. The name Stenoclavelia 
was proposed for such males.

strongly convex, in front view with the apex strongly and broadly 
arcuately concave; mandible (when not eroded) about 0.80 as long as 
the clypeus is wide, its apical tooth moderately broad; propodeum 
without distinct wrinkles. 

Black. Body pubescence blackish; wings either entirely blackish 
or largely orange-yellow, according to the subspecies. 

There are two subspecies, differing only in wing color. It may be 
presumptuous to consider two forms subspecies without evidence of 
intergrades where their ranges approach, but with their ranges adja- 
cent and orly one character distinguishing the two populations, it 
seems reasonable to suppose that intergrades or other evidence of 
natural interbreeding will eventually come to view. An exactly 
similar situation occurs between the two forms here considered sub- 
species of Cryptocheilus idoneum.

PEPSINAE: TRIBE PEPSINI 73 


Wings orange-yellow, the apical 0.25+ of the forewing and the 
apex of the hind wing blackish. 

This subspecies is one of three species or subspecies of Cryptocheilus 
agreeing moderately well with Say’s description and figure of Pompilus 
terminatus and all three plus others have been identified as terminatus 
by various workers. The present form is the only one with the apical 
dark area of the forewing as wide as described by Say and the name 
terminatum thus seems applicable to it alone. 

Specimens (300, 519): From Alberta (Lethbridge); Arizona

Genus Priocnemis Schigdte 


Medium or small sized species of slender to stout build, the fore- 
wing of the Nearctic species 3 to 13 mm. long; clypeus rather small 
for the Pepsini; pronotum of moderate length, its hind margin broadly 
angled to a weak median notch; second intercubital vein strongly 
curved and oblique posteriorly, nearly straight and perpendicular an- 
teriorly; second recurrent vein reaching second cubital cell near its 
middle; cubital vein often fading out before the wing margin; base 
of first discoidal cell without an irregularity in the membrane; ner- 
vulus beyond basal vein by about 0.7 to 1.3 its length; nervellus end- 
ing some distance before juncture of cubitella with discoidella; anal 
lobe elliptical, about 0.35 to 0.55 as long as submediella (pl. 1, fig. 7); 
hind tibia either smooth or serrate dorsally, always serrate in females 
of the Nearctic species; brush on inner side of hind tibia of moderate 
width, without a subapical constriction; last segment of tarsi beneath 
without preapical bristles in the Nearctic species, in some exotic 
species with a few, rather irregularly rowed bristles; tooth on tarsal 
claws small, erect, acute. 

This genus is mostly Holarctic, but the subgenus Sphictostethus has 
a marsupial type of distribution. The four recognized subgenera are

Subgenus Sphictostethus Kohl 


Sphictostethus Kohl, 1884, Verh. zool.-bot. Ges. Wien, vol. 34, pp. 37,47. Type: 
Pompilus gravesii Haliday; original designation. 

Haploneura Kohl, 1884, Verh. zool.-bot. Ges. Wien, vol. 34, pp. 37, 47 (preoc-

tion. 

Haploneurion Kohl, 1885, Ent. Nachr., vol. 11, p. 163 (new name for Haploneura). 

In specimens with functional wings, the third intercubital vein 
slants outward so that the third cubital cell has its outer angle acute 
(pl. 2, fig. 21); the third cubital cell is variable in size, usually about 1.2 
as long as the second, and the cubital vein usually reaches the wing 
margin. The wings of the females of some species are reduced, and 
in these species there are various distortions from the normal venation, 
including loss of the first intercubital vein. Upper edge of hind tibia 
of both sexes without or with teeth, the teeth when present usually 
weak, and never strong in the male; clothing hairs on upper edge of 
hind tibia not more sparse than on the front face of the tibia; pro- 
podeum without a sublateral longitudinal impression; male sub- 
genital plate often with a longitudinal compressed tooth. 

I have seen a number of species from Chile, some from New Zealand, 
one from Fiji, one from New Caledonia, five from México, and one 
from the Nearctic region. The Nearctic species (P. pretiosa) and 
the five from México form a distinct group which I shall call the 
pretiosa group. The determined extralimital species that have been 
examined are: Pompilus gravesii Haliday 1836; Salius (Priocnemis) 
thaumastarius Kohl 1905; Pompilus flavipes Guerin 1836; Agenia 
ranthopus Spinola 1851; Haploneuria apogona Kohl 1884; Haploneurion

the New Caledonian montrouzieri are from Chile and all are new com- 
binations in the genus Priocnemis or in the subgenus Sphictostethus, 
or in both.

This species occurs at 5,000 to 9,100 ft. in the mountains of New 
Mexico, Arizona, and adjacent México. 


Subgenus Clistoderes Banks 


Clistoderes Banks, 1934, Proc. Amer. Acad. Arts Sci., vol. 69, p. 33. Type: 
Priocnemis (Clistoderes) astarte Banks; original designation. 

This subgenus contains three species described from the Philippines 
by Banks in 1934. The long third cubital cell, sublateral grooves on 
the propodeum, and failure of the cubital vein to reach the wing margin 
are its outstanding characters. 


Subgenus Priocnemissus Haupt 


Priocnemissus Haupt, 1949, Beitrége zur taxonomischen Zoologie, vol. 1, p. 75. 
Type: Procnemis “coriarius’’ Dahlbom = coriaceus Dahlbom; original desig- 
nation. 

In the groove between the mesoscutum and scutellum slender 
slightly elevated wedges extend mesad but do not meet medially; 
third intercubital vein slanting outward so that the third cubital 
cell has its outer hind angle acute; third cubital cell about 1.2 as 
long as the second cubital cell; cubital vein reaching the wing margin 
(pl. 1, fig. 7); wings of both sexes functional; hind tibia of male with 
distinct teeth on its upper edge, of the female with strong, suberect, 
lobelike teeth; hind tibia of female almost hairless between the teeth 
so that its upper edge appears polished; propodeum without a distinct 
sublateral longitudinal impression. 

This subgenus is well represented in Eurasia and has three species 
in North America. All three of these are adults in the spring, being 
among the first psammocharids to begin flying and the first to disap-

that have been studied are the Chilean Salius (Priocnemis) disperti- 
tius Kohl 1905; the Colombian Priophanes moesta Banks 1945; and 
the European Priocnemis mimulus Wesmael 1851, Sphex fusca Fabri-

Black. Wings lightly to strongly infuscate; abdomen black. 
Specimens from the Pacific States and British Columbia have the 
wings averaging a little darker than in specimens from the East. 

This species is considerably more slender and with less long hair 
than the other two Nearctic species of the subgenus, and in these 
characters is more like a large group of Eurasian species.

Minn. Flower records include one collection on blueberry, three on 
Benzoin aestivale, and one on Prunus serotina. On two occasions 
specimens were taken at ‘sugar’ put on tree trunks for collecting 
moths. Adults appear with the first spring flowers and disappear 
in early summer. The habitat is woods, usually in sun-warmed 
stream bottoms. The adults run or fly low over the forest floor, and 
lack of concealing foliage at this early season makes them conspicuous. 
Soon after the trees are in full leaf they begin to disappear. 

This species occurs in the Alleghenian and Carolinian faunas of 
the eastern half of the continent, and in the Transition fauna of the 
Pacific Northwest. Its habitat is woods, the adults being present 
from early spring to early summer.

date, and possibly the last two dates apparently represent precocious 
spring arrivals rather than late stragglers. A female collected Apr. 
10, 1902, at Mountain View, Calif., is labeled “from nest of ground 
spider.” 

This is a spring species common in the Transition and Canadian 
faunas from southern British Columbia to southern California, and 
less common eastward into the Great Basin. 


Subgenus Priocnemis Schigdte 


Priocnemis Schigdte, 1837, Krgyer’s Naturhistorisk Tidsskrift, vol. 1, p. 324. 
Type: Sphezx exaltata Fabricius; designated by Westwood, 1840. 
Prionocnemus Burmeister, 1872, Stettiner Ent. Zeitung, vol. 33, p. 235 (emendation). 
Prionocnemis Kirby, 1884, Zool. Rec., vol. 20 (Insecta), p. 131 (emendation). 
Myrmecosalius Ashmead, 1903, Proc. Ent. Soe. Washington, vol. 5, p. 307 (new 
synonymy). Type: Myrmecosalius nigriceps Ashmead; monobasic. 

In the groove between the mesoscutum and scutellum slender 
slightly elevated wedges extend mesad from each side and meet at 
the middle, forming a narrow raised transverse line; third intercubital 
vein approximately perpendicular so that the third cubital cell has 
its outer angle approximately rectangular or obtuse; third cubital cell 
about as long as the second cubital cell; cubital vein sometimes not 
reaching the wing margin (pl. 2, figs. 22, 23, 24, 25); wings of the 
females of some species reduced or vestigial; hind tibia of male without 
a trace of teeth on its outer edge, of female with a row of sharp, 
obliquely chevron-shaped, decumbent teeth; hind tibia of female with 
numerous hairs on and between its teeth, so that its outer edge does 
not appear polished; propodeum without a sublateral longitudinal 
impression. 

This subgenus is well represented in both North America and in 
Eurasia, and there are a few species in the Neotropics.®, In contrast to 
the vernal subgenus Priocnemissus, adults of the subgenus Prioenemis 
occur in the summer. The extralimital species of which specimens 
have been studied are: Pompilus parcus Cresson 1867 (Cuba); the 
European Sphex erxaltata Fabricius 1775, Pompilus minutus Linden 
1827, Pompilus femoralis Dahlbom 1829, Priocnemis parvulus Dahlbom 
1845, Prioenemis obtusiventris Schigdte 1837, Pompilus pusillus Schigdte 
1837, Calicurgus propinquus Lepeletier 1845, and Salius schenckir 
Kohl 1884; an undetermined Chilean species; and two undetermined 
species from México related to P. navajo. 

In 1951 (U. S. Dep. Agr., Agr. Monogr. No. 2, pp. 913-914) the 
subgeneric name Priocnemis was erroneously applied to Priocnemissus 
and true Priocnemis was called Myrmecosalius. The error originated 
with specimens of a European species of Priocnemissus misdetermined 
as Priocnemis exaltata, the genotype of Prioenemis, which gave a false 
idea of the proper application of this name.

Mate: Forewing 4 to 7 mm. long; clypeus with the apical margin 
specialized, the specialization varying from a sublateral thickening or 
weak impression of the margin to a very large deep pit in the same 
position; frons subpolished, with sharp punctures separated by about 
0.2 their diameter. The stronger specialization of the clypeus occurs 
usually in larger males. In these there is a tendency for the clypeus 
to be narrower than usual and the head is always swollen postero- 
dorsally. In ail other Nearctic species of this subgenus the apical 
margin of the clypeus is simple and sharp in both sexes and the head 
is of normal shape. Middle third of sixth sternite smooth; exposed

Collection dates are mostly from June 1 to Sept. 15, with a con- 
spicuous concentration in July and August and precocious and 
straggling individuals a few weeks outside of this range as: Apr. 16 
at Takoma Park, Md.; Apr. 31 on the Patuxent River, Md.; May 13 
at Falls Church, Va.; May 24 at Clinton, N. C.; May 26 at Cabin

Sept. 16 at Cabin John, Md., and at Washington, D. C.; Sept. 23 at 
Bolivar, W. Va.; Oct. 1 at Arlington, Va.; and Oct. 13 on Plummers 
Island, Md. North of the vicinity of Washington, D. C., the dates 
of collection do not extend so late into the fall, as indicated by the 
extreme dates of Sept. 8 at Englenook, Pa., and Sept. 14 at Phila- 
delphia, Pa. Twelve of the collections are labeled as having been 
made in woods and my own experience is that the species occurs 
almost exclusively in the herbs and shrubbery of mesophytic and 
moist deciduous woods.

Ranunculus californicus, Daucus carota, and Bifora americana. Seven 
of the collections were made “‘on sand” and one ‘“‘in woods.”” My own 
observations indicate that the usual habitat is rather bare ground in 
the open, often somewhat sandy. 

This species occurs in the entire United States and southern Canada. 
The usual habitat is bare or rather sparsely covered ground in the

Black. Apical half of mandible rufous; wings infuscate. 

The male of this subspecies is indistinguishable from that of P. 
notha occidentis. 

Frmaue: Forewing 4.5 to 7.5 mm. long; frons subpolished, with 
rather coarse punctures separated by about 0.5 their diameter. 

Black. Apical half of mandible rufous; wings strongly infuscate. 

SPECIMENS (429): From Arizona (Mormon Lake and the Santa 
Catalina Mts. at 5,500 ft., 6,000 ft., 7,500 to 8,500 ft., 8,000 ft., and 
9,000 ft.); California (Berkeley, Buck Creek in Modoc County, 
Carmel, Felton, Lands End in San Francisco County, Mount Love 
in San Francisco County, Mokel Hill in Calaveras County, Mount 
Tamalpais, Orick, hills back of Oakland, “Redwood” in Marin 
County, San Bruno, San Rafael, San Mateo, Tracy, and Yorkville); 
Colorado (Rabbit Ears Pass at 9,500 ft.); New Mexico (Cloudcroft 
at 9,000 ft.); Oregon (Klamath Lake); Washington (Forks); and 
México (meadow valley in the Sierra Madre). 

Most dates of collection are in June through August, or in the 
warmer parts of the range, from May 15 through August. Dates 
outside of the latter range are: May 1 at Yorkville, Calif.; May 7 at 
Berkeley, Calif.; Sept. 21 at Tracy, Calif.; Oct. 1 at Carmel, Calif.; 
and Oct. 27 at Berkeley, Calif. A number of males collected together 
with these females make an unquestionable association of the sexes, 
but they are indistinguishable from males of the subspecies occidentis. 
Some additional males from the same general area as the females 
represent additional specific localities, but are not reported because 
they do not in themselves give proof of the distribution of the 
subspecies. 

This subspecies occurs in the Canadian and Transition Zones from 
the Pacific to the Rocky Mountains.

This subspecies occurs in the Transition and Upper Austral Zones 
from the Atlantic Ocean to the Rocky Mountains. Farther westward 
it is replaced by other subspecies. Adults are common in the summer 
and the first half of fall. 


Genus Calicurgus Lepeletier 


Calicurgus Lepeletier, 1845, Histoire naturelle des insectes, hyménoptéres, 
vol. 3, p. 397. Type: (Pompilus fasciatellus Spinola) = hyalinatus Fabricius; 
designated by Kohl, 1884. 

Caliadurgus Pate, 1946, Trans. Amer. Ent. Soc., vol. 72, p. 78. Type: Sphezx 
hyalinata Fabricius; original designation. (For my reasons why the name 
Caliadurgus is not adopted see U. S. Dep. Agr., Agr. Monogr. No. 2, p. 
915, 1951.) 

Agreeing with the description of the genus Priocnemis except: 
Forewing of Nearctic species 4.5 to 8.5 mm. long; pronotum very 
short; fore tibia of female with a single, very stout, blunt, spinelike 
bristle at its outer apical corner (this stout bristle is not present in 
other Pepsini); cubitus reaching wing margin; nervulus at the basal 
vein, or beyond it by less than 0.3 of its length; anal lobe subtriangular, 
much of its posterior margin straight (pl. 1, fig. 8); dorsal edge of 
hind tibia of female with a chevron-shaped row of teeth, of male 
smooth; last segment of tarsus without preapical bristles beneath. 

There is but one polytypic Nearctic species, which is considered 
conspecific with the common Palaearctic C. hyalinatus. However, 
the genus is well represented in the Neotropics. I have seen the types 
of the Neotropic Priocnemis christophei Banks, Pricenemis (Cali- 
curgus) doddsi Banks 1925, Calicurgus andicolus Banks 1946, Calicurgus 
jocaste Banks 1946, Calicurgus loranthe Banks 1946, Calicurgus 
marginatus Banks 1946, Calicurgus orijones Banks 1946, Calicurgus 
quitus Banks 1946, Calicurgus rufigaster Banks 1946, Pompilus 
(Priocnemis) impiger Cresson 1869, and Pompilus pulchellus Cresson 
1865, and the oriental Priocnemis (Calicurgus) ariel Banks 1934. 
All these and doubtless most of the other Neotropic species now 
standing in Calicurgus are correctly placed in this genus. With such 
a rich representation in the Neotropics, one could expect the eventual 
discovery of additional Nearctic species along our southern border. 


PEPSINAE: TRIBE PEPSINI 109 


1. Calicurgus hyalinatus Fabricius 


Matz: Forewing 4.5 to 6.5 mm. long. Black. Tibial spurs and 
a large spot on last tergite white; clypeus, hind margin of pronotum, 
and apex of fore coxa marked with white in some subspecies; femora 
and tibiae with various amounts of rufous; wings hyaline, the apical 
margin of the forewing faintly infuscate. 

Fema.e: Forewing 5.5 to 8.5 mm. long. Black. Femora, tibiae, 
and abdomen with various amounts of rufous according to the sub- 
species; wings hyaline, the forewing with a large subapical fuscous 
spot and in some subspecies a narrow infuscation along the basal 
vein and the apical margia weakly infuscate. In the subspecies 
excoctus the subapical and the basal infuscate areas are confluent. 

This species is Holarctic, with four subspecies in the Nearctic 
Region. The typical subspecies (C. hyalinatus hyalinatus Fabricius 
1793) has a wide range in the Palaearctic Region. It is rather similar 
to the Nearctic C. hyalinatus borealis, differing in the male in the re- 
duction or loss of the white markings on the clypeus, pronotum, and 
fore coxa, and in the slightly different distribution of the rufous color 
on the femora and tibiae; and differing in the female in having the 
black on the legs averaging a little more extensive and in the forewing 
a tendency toward more infuscation along the basal vein. 

In the eastern half of the United States this is a conspicuous and 
common species during middle and late summer among low dense 
vegetation of moist woods.

9, Stony Brook Reservoir, Mass., June 21, 1925 (Cambridge). 


Mate: Black. Palpi brown; mandible variably colored with 
white, brown, and black; clypeus with the apical edge and a connect- 
ing pair of large lateral spots white; hind margin of pronotum, usually 
the front apex of the fore coxa, and an indistinct spot on apex of 
fore tibia behind, white; femora, tibiae, and front and middle tarsi 
fulvous to light brown, the femora basally infuscate and the middle 
and hind tibiae, especially the hind, more or less infuscate basally 
and apically; hind tarsus dark brown. The extent of basal infusca- 
tion on the femora varies from a narrow basal ring to more than 
0.6 the length. The infuscation is usually most extensive on the front 
femur. 

FrMae: Black. Mandible with its apical 0.4+ dull rufous; apices 
of femora and of tibiae with dull rufous stains; hind femur varying 
from half rufous and the rest rufo-fuscous or blackish to entirely 
black except usually for an apical rufous stain; hind tibia often ex- 
tensively stained with rufous; abdomen with the basal two to three 
segments rufous, the base of the first segment black. Wings sub- 
hyaline, the forewing with the typical fuscous markings, including a 
distinct fuscous mark over the basal vein. 

This is the northernmost Nearctic subspecies and the one closest 
to the Palaearctic subspecies hyalinatus hyalinatus. It and the 


PEPSINAE: TRIBE PEPSINI 111 


neighboring subspecies in the Transition and Upper Austral Zones 
(hyalinatus alienatus) intergrade freely and collections from localities 
bordering between Canadian and Transition usually contain speci- 
mens assignable (on the division adopted here) to both subspecies.

head); Maine (Bangor, Brooksville, Lincoln County, Monroe, and 
Orono); Massachusetts (Cummington, Newton Center, Sagamore, 
and Stony Brook Reserve); Michigan (Ann Arbor, Roscommon

(Seattle and Westport). Collection dates are mostly from June 22 
to the end of August. Those outside of this range are: June 9 at 
Woodhaven, Long Island, N. Y.; Sept. 3 at Tuckerman’s Ravine on 
Mount Washington, N. H.; Sept. 19 at Seattle, Wash.; and Sept. 25 
at Orono, Maine. A number of males collected within the range of 
this subspecies are not reported here because only their locality data 
would permit a definite assignment to a subspecies. 

This subspecies is transcontinental in the Canadian Zone and the 
cooler parts of the Transition Zone. The flight period is mostly from 
June 22 to Aug. 31.

fuscous at the base and sometimes diffusely infuscate on up to half 
its area (if more extensively infuscate, the specimen is assigned 
to the subspecies borealis); hind tibia more or less infuscate basally 
and apically, always with at least a faint infuscation on the inner side 
near its apical 0.25; abdomen rufous, blackish at the base and black 
to rufo-fuscous beyond the third segment. Wings subhyaline, the 
forewing with the usual subapical and apical infuscation and with 
or without a weak infuscation along the basal vein. 

This subspecies occupies typically the Alleghenian and Carolinian 
faunal areas. At the northern and southern edges of its range it 
intergrades freely with the subspecies borealis and rupex respectively, 
and occasional individuals with the typical coloration of these two 
occur well within the range of the present subspecies.

Genus Dipogon Fox 


Small sized, stout species, the forewing 2.3 to 10 mm. long; clypeus 
broad and short; mandible with 3 teeth, counting the apical point (in 
all other Nearctic Pepsinae, the mandible has only 2 teeth); cardo of 
maxilla of female with a fascicle of long hairs curving to and approxi- 
mately reaching base of mandible (this fascicle is lacking or undevel- 
oped in all other Psammocharidae); pronotum long, flat, its hind 
margin arcuate; second intercubital vein curved, oblique; second 
recurrent vein reaching second cubital cell at its basal 0.3 to 0.45; 
cubital vein reaching the wing margin in all species but those of the 
pulchripennis group; base of first discoidal cell without an irregularity 
in the wing membrane; nervulus beyond the basal vein by about 0.2 to 
0.3 its length; nervellus ending some distance before the juncture of 
cubitella with discoidella; anal lobe about 0.35 as long as submediella 
(pl. 1, figs. 9, 10); hind tibia smooth dorsally, the brush on its inner 
side moderately broad, without a subapical constriction; last segment 
of tarsi without preapical bristles; tooth on tarsal claws small, erect, 
and acute. 

The species of Dipogon probably all nest in holes in wood. The 
females of the subgenus Deuteragenia are taken most often on stumps 
and the trunks of dead trees, while those of the subgenus Dipogon are 
more frequent on smalier twigs and branches. The dark bands on the 


116 U. S. NATIONAL MUSEUM BULLETIN 209 


forewing of most species give the appearance of the node and gaster 

of the Formicidae, and when seen running on trunks or twigs indi- 

viduals of these species look very much like specimens of Camponotus. 
The two subgenera are easily distinguished.

122 U. S. NATIONAL MUSEUM BULLETIN 209 


Dates of collection are distributed from midspring to midfall, with 
apparent peaks of abundance in June and in September. Unusually 
early and late dates are: May 8 near Tigerville, S. C.; May 22 at 
Great Falls, Va.; May 28 on Plummers Island, Md.; Oct. 15 at State 
College, Pa., and at Arlington, Va.; and Oct. 24 in Brazos County, 
Tex. Other biological data with these specimens state that two dif- 
ferent collections were made in woods; that a male emerged on Mar. 
25 from material collected on Feb. 27 at North Cumberland, Pa., by 
Kirk and Champlain; that a male emerged on June 2 from Carya 
wood collected at Linglestown, Pa., by W. 5. Fisher; that a male and 
a female emerged in June from Carya wood collected at Forest Hills, 
Mass.; that a male emerged from Fagus grandifolia wood collected at 
Durham, N. C., by Wm. Haliburton and J. A. Beal; and that a female 
from Manhattan, Kans., was taken by H. E. Evans while trans- 
porting prey (Paraphidippus aurantius) over a dried stream bed. 

This subspecies occurs in the Canadian, Transition, and Upper 
Austral Zones from the Atlantic to the 100th meridian. It occurs in 
woodlands and nests in dead wood. Adults are on the wing from 
midspring to midfall. 


2c. Dipogon (Deuteragenia) papago floridanus, new subspecies 


Mauu: Forewing moderately infuscate, a little more hyaline basally

Va.; Sept. 20 at Montreal, Quebec; Sept. 23 at Wakefield, Conn.; 
and Oct. 7 and 10 at Arlington, Va. Other biological notes with 
these specimens state that a female was taken on flowers of Geranium 
maculatum; that six different collections were made in woods; that 
three collections (1c, 22) were made on tree trunks; that a female 
was reared from Carya wood at Syracuse, N. Y., July 6, 1918, by 
Blackman and Stage; and that a female was reared from Celtis wood 
at Plummers Island, Md., Apr. 25, 1908, by W. S. Fisher. 

This is a common woodland subspecies of the Alleghenian and 
Carolinian faunas. It nests in dead wood, the females being com- 
monly seen on stumps and dead tree trunks. Adults are on the wing 
from late spring to early fall.

The two females taken at flowers of Pastinaca sativa by H. E. Evans 
at Ithaca, N. Y., July 6, 1947, are accompanied by the note that 
these and a few other specimens were walking along the stems just 
below the umbels, holding the wings more or less erect, and fanning 
them. They looked much like otitid flies, the bands on the wings 
increasing the resemblance. 

This subspecies occurs in the Carclinian fauna and the warmer 
parts of the Alleghenian fauna. Its usual habitat seems to be dry 
deciduous woods where the females may be found running along the 
twigs and small branches of shrubs and understory trees. In appear- 
ance, habitat, and manner of walking they look much like certain 
species of Camponotus (Formicidae).

Tribe Macromerini 


Cubital vein of forewing not quite reaching wing margin (pl. 1, 
fig. 11); hind tibia most frequently smooth, though in some females 
with an external dorsal serration; first abdominal tergite rather slender, 
somewhat constricted subbasally so that at least in females its sides 
are subbasally concave when seen from above; suture or fold separating 
epipleuron of first abdominal segment from the tergite usually absent; 
last tergite of male usually with a large whitish spot; parapenial lobe 
of male genitalia apically decurved to form a hook. 

This tribe includes many small, slender species and a few middle 
sized ones. The Old World genus Macromeris contains large, rather 
robust species. Many of them, including all species of the Nearctic 
genera Auplopus and Phanagenia, make mud cells for nests. The 
nesting habits of the other two Nearctic genera (Ageniella and Priocne- 
mella) are practically unknown. A curious propensity of this group 
of wasps is to cut off all or most of the legs of the prey before trans- 
porting it to the nest. 


Key to the Nearctic genera of Macromerini 


1. First tergite with a fine lateral crease that separates off the epipleuron; propo- 
deum without long erect hairs; mentum of female with a brush of about 20 
long stout bristles which are not divided into right and left groups; under- 
side of last tarsal segment of female with preapical bristles. 

Phanagenia (p. 141) 

First tergite without a lateral crease; propodeum with or without long erect 
hairs; mentum of female with either slender hairs, or with stout bristles that 
are divided basally into right and left groups. .. . Rot ak 

2. Propodeum with long erect hairs; female with a bare pyEidial area and with 
some strong bristles arising from the mentum; male subgenital plate rather 
large, with a high, sharp, longitudinal ridge . ... . Auplopus (p. 148) 

Propodeum usually without long erect hairs; female without a pygidial area 
and with only slender hairs arising from the mentum; male subgenital plate 
smaller, or its longitudinal ridge (when present) lower and more blunt. . 38 

3. Apex of front tibia on the hind side without a conspicuously larger or re- 
curved spinelike bristle; clypeus without a troughlike impression paralleling 
its lateroapical margin . . . ... . . Ageniella (p. 167) 

Apex of front tibia on the hind fide Sreaomarl by a conspicuously larger and 
recurved spinelike bristle (best developed in the female); clypeus with a 
troughlike impression paralleling its lateroapical margin.

Auplopus; mentum of female with a brush of about 20 long stout 
setae which are not parted into right and left groups; front tibia with- 
out one of its apical bristles specialized; dorsal edge of hind tibia 
smooth; last tarsal segment without distinct preapical bristles be- 
neath in the male, but with them in the female; propodeum without 
long erect hairs; first tergite with a fine line or fold separating off the 
epipleuron; female with an oval, bare pygidial area. 

Phanagenia is close to the large and variable genus Auplopus, but in 
the Western Hemisphere, where it is represented only by the geno- 
type, it is distinct in the characters mentioned in the key. Old World 
species that might be referable to Phanagenia are as follows: An un- 
determined African species represented in Cambridge by two females 
seems to be a typical Phanagenia; the Madagascan Agenia macula 
Saussure 1891, as represented by both sexes in Cambridge (deter- 
mined by Banks), may be a Phanagenia but the mental bristles of the 
female are rather sparse and male clypeus simple; the Australian 
Fabriogenia incompta Banks 1941, represented by the female type in 
Cambridge, has the mental bristles and bristles on the under side of 
the fifth tarsal seements as in Phanagenia, but lacks the suture sepa- 
rating the epipleuron of the first tergite.

The depth of infuscation on the wings is correlated with size (darkest 
in the largest specimens) and distribution (darkest in the specimens 
from farthest south). Somewhat similar correlations of the depth of 
wing infuscation with size and distribution occur in the species 
Priocnessus nebulosus.

Clypeus of male of moderate size, its apical edge usually truncate 
but sometimes variously specialized; clypeus of female large, convex, 
the apex somewhat prolonged as a broadly rounded lobe; mentum of 
female with a group of about 6 to 16 long stout setae which are 
parted basally into right and left groups; front tibia without one of 
its apical bristles specialized; dorsal edge of hind tibia smooth; last 
tarsal segment without preapical bristles beneath; propodeum nearly 
always (always in the Nearctic species) with long sparse erect hairs; 
first tergite without a line separating off the epipleuron; female with 
an oval hairless pygidial area; male subgenital plate rather large, 
with a high sharp longitudinal ridge. 

Spinola included only one species in his genus Awuplopus, the 
Fabrician Pompilus femoratus. He noted some disagreements in 
color between his specimens and Fabricius’ description of femoratus, 
but nevertheless referred them to this species. Richards (1937, 
The generic names of British insects, vol. 5, p. 126) states that Spinola’s 
“variety” of femoratus, rather than femoratus itself, is the type of 
Auplopus and Pate (1946, Trans. Amer. Ent. Soc., vol. 72, p. 76) 
concurs. It seems clear, however, that for nomenclatorial purposes 
the one species originally included was Fabricius’ Pompilus femoratus, 
and this must be the type species. 

The original description of Pompilus femoratus is not sufficient for 
a modern generic assignment, but Dahlbom (1843-45, Hymenoptera 
EKuropaea . .. , vol. 1) examined the type and indicated its generic 
characters in the following way: On page 93 (1843) he describes 
Agenia fuloipes from females from Pennsylvania and South Carolina, 
mentioning the polished pygidium and clypeal shape so characteristic 
of the present genus. On page x1x (1845?) he states that he has 
studied the type of Pompilus femoratus, and on page 455 (1845) he 
synonymizes his fuluipes with femoratus, thus indicating that the 
type of femoratus had the pygidial area and clypeal shape he described 
for fulvipes and that otherwise the types appeared conspecific to him. 
Dahlbom’s fulvipes can be none other than the Nearctic species 
mellipes Say, but I suspect that femoratus (described from South 
America) is a distinct though closely related species. The original 
description of femoratus states that the femora are ferruginous and 
the rest of the legs blackish. In mellipes mellipes the legs beyond 
the coxae are entirely ferruginous. There are several common 
Neotropical species which greatly resemble mellipes but which differ 
from it in the leg colors called for in the description of femoratus. 

Auplopus is a very large genus, best represented in the warmer 
parts of the world. In the Old World tropics the species have much 
structural diversity and Banks has considered some of the more 
conspicuous segregates genera, as indicated in the synonymy above. 


PEPSINAE: TRIBE MACROMERINI 145 


The New World species have more structuraluniformity. Thereare 
many species in the Neotropic region and a large portion of the 
Nearctic species are intrusions from that area. It has not been 
possible to separate our species into sharply defined groups, but the 
following resemblances might be pointed out: A. flavicorae, inermis, 
variolarum, and adjunctus agree in the polished female pygidium, 
lack of bluish iridescence, fulvous femora and tibiae, and unspecialized 
mandible and clypeal margin of the male. <A. mellipes and mexicanus 
agree in the mat female pygidium, lack of bluish iridescence, bent 
mandible of the male, and thickened apical margin of the male clypeus. 
A. mollis, caerulescens, architectus, and nigrellus agree in the polished 
female pygidium, presence of bluish iridescence, and the unspecialized 
mandible and clypeal margin of the male. 

Probably all species of the genus nest in mud cells and the charac- 
teristic mental bristles and large clypeus of the female are presumed 
to aid in carrying mud pellets for nest construction. Absence of 
teeth on the outside of the hind tibia seems to be another structural 
character correlated with these nesting habits, but the functional 
reason is not entirely clear. Possibly the tibial teeth when present, 
aid in digging or in pushing into and out of nest tunnels in the ground 
and, if so, would not be needed in species making nests of mud cells.

angled to a rounded median point; second flagellar segment about 
6.0 as long as wide; groove of pronotum with fine, weak, oblique 
wrinkles; pygidial area polished, without evident punctures. 

Black, without iridescence. Apical part of mandible rufous; palpi 
pale brown, darker basally, underside of flagellum tinged with fulvous 
apically; tegula reddish brown; legs fulvous, the last tarsal segment 
brown; wings faintly to rather strongly infuscate.

The infuscation of the wings varies with the locality, being darkest 
in Florida and paler northward and westward. Most specimens from 
the Carolinian fauna are definitely paler winged than most of those 
from the Austroriparian. The infuscation of the wings of males 
varies somewhat in the same direction; but the wings are never more 
than faintly infuscate, so the locality differences are less conspicuous 
than in females. 

Specimens (190, 639): From Alabama (Wadley); District of 
Columbia (Washington); Florida (Monticello, Orange County, Or- 
lando, and Tarpon Springs); Georgia (Atlanta, Billys Island in the 
Okefenokee Swamp, Stone Mountain, Thomasville, and Tifton); 
Louisiana (Opelousas); Maryland (Cabin John, Glen Echo, and 
Takoma Park); North Carolina (Elizabethtown, Fayetteville, John- 
ston County, Murfreesboro, Raleigh, and Wallace); South Carolina 
(Columbia, Greenville, and McClellanville); and Texas (Brazos 
County, Fedor, Kerrville, and New Braunfels). 

The collecting dates are scattered from midspring to early fall, 
unusually early and late dates of interest being Mar. 19 at Tarpon 
Springs, Fla.; Apr. 30 at Elizabethtown, N. C.; May 11 at Raleigh, 
N. C.; Sept. 4 at Greenville, S. C.; Oct. 138 at Murfreesboro, N. C.; 
and Nov. 9 in Brazos County, Tex. In my own collecting experience 
the species is often moderately common in the undergrowth of damp 
bottomland woods. A female in the Strandtmann collection was 
reared ‘‘11-9-35” from a mud cell found near the Brazos River, Texas. 

This species occurs in the Gulf and Atlantic States from Texas to 
Maryland, the habitat being damp bottomland woods. Adults fly 
from midspring to early fall.

Mate: Forewing 5.5 to 7.5 mm. long; apical margin of clypeus 
straight medially, angularly produced laterally, between the lateral 
corners much thickened (see from below); mandible with a strong 
bend at the middle; second segment of flagellum about 4.0 as long as 
wide, the penultimate segment about 2.8 as long as wide; mesopleuron 
with dense, fine, subadjacent punctures, a little shining, its pubescence 
rather short. 

Black. Face and clypeus except often for a narrow median stripe, 
lower lateral corner of frons, underside of scape, mandible except at 
the base and apex, and a large median spot on seventh tergite, white;

polished background; apical margin of clypeus broadly angled to a 
rounded median point; second flagellar segment about 4.8 as long as 
wide; groove of pronotum with rudimentary fine, oblique wrinkles; 
pygidial area mat, apically with scattered punctures that are separated 
by about 2.5 their diameter. 

Black, without iridescence. A very narrow line on inner orbit 
fulvous; flagellum fulvescent beneath; apical part of mandible ferrugi- 
nous; palpi pale brown, darker basally; tegula brown; coloration of 
rest of legs varying with the subspecies; wings subhyaline. 

There are three subspecies, differentiated on the basis of leg colora- 
tion, all in the eastern half of the United States and Canada.

Paris, and Victoria); and Virginia (Arlington, Chain Bridge, Dead 
Run in Fairfax County, Dunn Loring, Falls Church, Lake Drummond, 
Little Bald Knob in Augusta County, Mount Vernon, and Rosslyn). 

The specimens at hand from Put in Bay, Ohio and Pelee Island, 
Ontario, and one from Carver County, Minn. are intermediate to the 
subspecies varvitarsatus. 

Dates of capture are rather evenly distributed from late spring to 
midfall, unusually early and late dates being Apr. 4 at Commerce, 
Tex.; Apr. 11 at Marianna, Pa.; Apr. 24 at Plummers Island, Md.; 
Apr. 30 at Raleigh, N. C.; May 2 at Atlanta, Ga.; Sept. 27 at Onaga, 
Kans.; Oct. 20 at Washington, D. C.; Nov. 13 in Pasco County, Fla.; 
and Dec. 23 in Orange County, Fla. This species is commonest in 
moist woods. 

Rearing records are as follows: Two males on Apr. 4, 1939, from a 
mud nest taken at Commerce, Tex.; a male and two females on 
July 14, 1946, from a mud nest taken at Victoria, Tex.; two males 
and a female on May 21 and 25, 1917, from a nest in a vial taken at 
Plummers Island, Md., by H. L. Viereck; a male on Aug. 20, 1945, 
from an old Trypoxylon politum nest taken in Maryland by Morton 
Vogel; and some specimens in the U. 5. National Museum from an 
abandoned Polistes comb collected by J. C. Bridwell. Rau records 
it using various holes and crevices, especially old nests of Sceliphron 
caementarium, which serve both as sources of building material and 
as crannies for its own mud cells. Females are very frequently found 
in houses, probably entering in search of nesting sites. Rau records 
Phidippus sp. and Pisaurina undata as prey, and Chrysis pattoni as 
a social parasite. 


154. U. S. NATIONAL MUSEUM BULLETIN 209 


This subspecies occurs in the Carolinian and Austroriparian faunas, 
in woods. The dividing line between it and the subspecies varii- 
tarsatus seems to coincide with the farthest southward extent of 
glaciation. Adults are on the wing from late spring to midfall.

158 U. S. NATIONAL MUSEUM BULLETIN 209 


segment of flagellum about 3.2 as long as wide, the penultimate seg- 
ment about 1.9 as long as wide; mesopleuron mat, with fine close 
punctures, its pubescence of moderate length, whitish and conspicu- 
ous; squama of genitalia unusually narrow and with an unusually 
strong median ventral protuberance. 

Fremaue: Forewing 5.0 to 7.0 mm. long; clothing hairs of frons pale, 
faintly broader and more conspicuous than in A. nigrellus and A. 
architectus, arising from fine subadjacent punctures on a mat back- 
ground; apical margin of clypeus broadly angled to a weak median 
point; second flagellar segment about 3.7 as long as wide; venation of 
forewing as noted in the key; groove of pronotum without distinct 
cross wrinkles; pygidial area polished, without evident punctures. 

Coloration of both sexes blackish brown with a weak (male) or 
strong (female) greenish blue iridescence which is strongest on the 
thorax; head, antenna, mouth parts, legs, and abdomen with variable 
amounts of fulvous coloration, according to the subspecies; tegula 
light brown. Male with the apical half of mandible, clypeus except 
for a median spot, face except for a median spot, lower lateral corners 
of frons, and a large median spot on the last tergite, white. Female 
with the apical half of the mandible fulvous. 

This is one of three Nearctic species with blackish legs and body 
with a bluish or greenish iridescence, the other two being architectus 
and nigrellus. Males are easily separated, but the females with diffi- 
culty. Some females of the present species have the legs partly ful- 
vous and these are easily recognized as belonging here, since neither 
architectus nor nigrellus ever have the legs thus marked. Females of 
caerulescens without fulvous on the legs are difficult and often impos- 
sible to differentiate. (See the comparisons of the three species in the 
key to females.) 

There are three subspecies as indicated below.

Marked with fulvous stains on antenna, front femur, tibia, tarsus, 
and apex of coxa. The fulvous markings are often extensive, approach- 
ing those of the subspecies caerulescens. The arbitrary division be- 
tween the two is whether the middle femur is mostly blackish (sub- 
species subcorticalis) or fulvous (subspecies caerulescens).

Ficure 87.—Localities for Auplopus caerulescens subcorticalis. 


Rearing records are as follows: 9, reared Apr. 2, 1907, from cell 
found under bark, Victoria, Tex., J. D. Mitchell; 3<7, reared Oct. 23, 
1931, from mud cells taken from pomegranate from México, J. D. 
Smith; o’, 9, emerged May 28, 1940, from material collected Feb. 10, 
1940, at Athens, Ohio. The type material of suwbcorticalis was from 
mud cells found under bark and this form was originally differentiated 
from A. architectus partly by the fact that the cells were placed under 
bark rather than under stones. 

The range of this subspecies covers most of the United States, 
southern Canada, and Northern México. It overlaps the range of 
the Southeastern subspecies caerulescens, but apparently not the range 
of the subspecies floridanus of Florida to South Carolina. Adults 
occur from late spring to early fall. The mud cells are placed under 
loose bark.

This is one of three Nearctic species of Auplopus with black legs 
and body and a strong iridescence, the other two being caerulescens 
and nigrellus. The three are easily separated in the male, but with 
difficulty in the female (see the comparisons in the keys). There are 
two subspecies of architectus—metallicus of the Pacific States and 
British Columbia and architectus mostly east of the Rocky Mountains. 


9a. Auplopus architectus metallicus (Banks) 


Pseudagenia metallica Banks, 1910, Journ. New York Ent. Soc., vol. 18, p. 125, 
Q. Type: 9, Claremont, Calif. (Cambridge). 


This subspecies differs in averaging a Jittle smaller, with darker 
iridescence, fewer long erect hairs, and the wings somewhat more

infuscate, especially in the female. See the keys for a more exact 
comparison. Specimens from New Mexico, Arizona, and northern 
México tend to be intermediate between this and the typical sub- 
species. 

SPECIMENS (43<7, 1339): From British Columbia (Kaslo, Midday 
Valley at Merritt, Salmon Arm, Steelhead, Vernon, and Victoria); 
California (Antioch, Berkeley, Brentwood, Carmel, Davis, E] Dorado 
County, Fairfax, Forest Home in San Bernadino County, Lafayette 
in Contra Costa County, Leavitt Meadows in Mono County, Mar- 
tinez, Menlo Park, Mill Valley, Mokelumne Hill, Morgan Hill, 
Murphys, Niles Canyon in Alameda County, Oakland, Patterson, 
Quincy, San Francisco, Santa Anna, Santa Clara, Saticoy, southern

Nevada (Reno); New Mexico (Beulah and Cloudcroft); Oregon 
(Baker, Brookings, Colestin, Corvallis, Eugene, Grave Creek in 
Josephine County, Hillsboro, Hood River, Lake of the Woods, and 
Siskiyou Pass in Jackson County); and Washington (Pialschie and 
Wawawai). 

Most dates of capture are from May to early in October. Unusu- 
ally early and late dates are: Mar. 27 at Berkeley, Calif.; Apr. 23 at 
Corvallis, Oreg.; Apr. 24 at Berkeley, Calif.; Oct. 9 at Corvallis, Oreg.; 
Oct. 10 at Whittier, Calif.; Oct. 15 at Davis and Fairfax, Calif.; 
Oct. 16 at Carmel and Ventura, Calif.; and Oct. 27 at Antioch, Calif. 
Biological data associated with these specimens are: 2 with prey 
(a salticid o), Lafayette, Contra Costa County, Calif., Sept. 9, 1948, 
KE. G. Linsley; and 9, bred from Pseudotsuga taxifolia, Pialschie, 
Wash., H. E. Burke. 

This subspecies occurs west of the Rocky Mountains, intergrading 
with the subspecies architectus in Colorado, Arizona, New Mexico, 
and northern México. 


9b. Auplopus architectus architectus (Say) 
PLATE 2, FIGURE 30 


Pompilus architectus Say, 1836, Boston Journ. Nat. Hist., vol. 1, p. 302 (Leconte 
edition, vol. 2, p. 744), 9. Type: 9, Ohio (destroyed). 

Biology: Walsh and Riley, 1869, Amer. Ent., vol. 1, pp. 132, 163.—Wickham, 
1898, Ent. News, vol. 9, p. 47. 


This subspecies differs in averaging a little larger, with paler iri- 
descence, more long erect hairs, and the wings nearly hyaline. (See 
the keys for a more exact comparison.) 

Say’s description of architectus includes a description of the nests 
and the places these are found. These biological notes fit the present 
species very closely and show that the name should be applied here 
rather than to nigrellus or caerulescens.

West Virginia (Bolivar); and México (Huanchinango in Puebla, 
Nombre de Dios in Durango, Sombrerete in Zacatecas, and Teoti- 
huacdn in “‘Pyr.’’). 

Specimens have been caught mostly from midspring well into the 
fall. The species seems particularly common during the first half of 
October. Early and late records of interest are: Feb. 22 in Eastland 
County, Tex.; Apr. 11 at Liberty Hill, Tex.; Apr. 2 at Greenville, 
S.C.; Apr. 25 at Parker Creek, Sierra Ancha, Ariz.; Apr. 27 at Cornelia, 
Ga., and Raleigh, N. C.; May 15 at Washington, D. C.; June 1 at 
Boston, Mass.; Oct. 9 at Mayo Beach, Md.; Oct. 21 at Raleigh, N. C.; 
Oct. 29 at Manhattan, Kans.; and Dec. 18 at Mobile, Ala. Biological 
notes with these specimens include one collection from nectaries of 
Ricinus communis; one collection at Quercus honeydew; one collection 
in woods; one collection ‘‘on forest floor’; one collection from sand 
along a stream; three different rearings from mud cells found under 
stones; two rearings from mud cells of unspecified origin; one with 


PEPSINAE: TRIBE MACROMERINI 165 


prey (Misumenops oblongus 9, with legs cut off) taken by H. E. Evans 
at Manhattan, Kans.; and another with prey (Phidippus audaz 
immature) taken by H. E. Evans at Ithaca, N. Y. In my own col- 
lecting experience this subspecies is common in pastures and aban- 
doned fields, rather than in woods as is the case with A. nigrellus. 
Its mud cells are somewhat more rotund and more perfectly made of 
harder clay than with certain other species. Always they are under 
a stone in the open, in an irregular group of usually three to five, 
plastered to the stone and against one another, in a place the stone 
happened to be raised above the soil enough to give the female space. 

This subspecies occurs in the Transition to Austroriparian Zones 
from the Atlantic to the Rocky Mountains and west of the Rocky 
Mountains into Colorado, New Mexico, and Arizona. It intergrades 
with the more western subspecies (A. architectus metallicus) in these 
three States and in northern México. Adults occur throughout the 
growing season, usually in overgrown fields. The nests are under 
stones in the open.

little concave, the apex thin and a little reflexed; mandible evenly 
curved; second segment of flagellum about 3.2 as long as wide, the 
penultimate segment about 1.65 as long as wide; mesopleuron mat,

with fine punctures, its pubescence moderately short, whitish, or 
dusky. 

Black. Head, thorax, and coxae with a dark greenish blue irides- 
cence; legs beyond coxae and abdomen with a similar but fainter 
iridescence; lateral 0.3-+ of clypeus and lateral 0.25+ of face whitish; 
palpi and tegula dark brown; wings subhyaline. 

Fema.e: Forewing 4.5 to 6.8 mm. long; clothing hairs on frons 
short and rather dark, arising from fine distinctly separated punc- 
tures on a mat background; apical margin of clypeus broadly angled 
to a rounded median point; second flagellar segment about 3.8 as 
long as wide; pronotal groove without distinct cross wrinkles; vena- 
tion as noted in the key; pygidial area polished, without evident 
punctures. 

Black, with a dark greenish blue iridescence, rather strong on the 
head and thorax, rather weak on the legs and abdomen; wings sub- 
hyaline. The iridescence of this species is usually a little darker 
than in architectus or caerulescens. 

Two other Nearctic species of Auplopus superficially similar to the 
present species are caerulescens and architectus. Males of the three 
are easily separated, but females with difficulty; females of nigrellus 
can usually be distinguished from those of architectus, but often not 
from those of caerulescens (see the comparisons in the keys). 

SPECIMENS (113 o', 779): from Arizona (Oak Creek Canyon); 
California (Claremont and the Mojave Desert); Colorado (Colorado 
Springs, Denver, and near Estes Park); Connecticut (Chester and 
East Hartford); District of Columbia (Washington); Iowa (Sioux

and Fort Davis); Vermont (Laurel Lake near Jacksonville); Virginia 
(Arlington, Dunn Loring, Great Falls, and Skyline Drive); and 
México (20 miles north of Comondt in Baja California). 

Collecting dates are from late spring to early fall, or May 10 to 
Sept. 15 in most of its range. Some dates of capture outside of this 
span are: Mar. 20 at Washington, D. C.; Apr. 2 at Eastland, Tex.; 
Apr. 12 at Claremont, Calif.; May 9 at Lawrence, Kans., and in the 
Mojave Desert, Calif.; Sept. 22 at Cabin John, Md.; Sept. 24 at 
Manhattan, Kans.; and Oct. 26 and 31 at Takoma Park, Md. Bio- 
logical data associated with the specimens are: one collection from 
pitch-pine honeydew; five collections in woods; two collections ‘‘on 


PEPSINAE: TRIBE MACROMERINI 167 


forest floor’; and a male reared May 9, 1911, from a mud cell found 
under a stone on golf links at Lawrence, Kans., by F. X. Williams. 
My own collecting experience indicates the typical habitat to be on 
or near the ground in rather open woods or along the edges of woods, 
usually in sunny spots. 

This species appears to occur in most of the United States, southern 
Canada, and northern México. Definite records from many of the 
southeastern states, and from the Northwest, except for a single 
capture in Oregon, are lacking. Adults occur on or near the ground 
in open woods or along the edges of woods. They are on the wing 
from late spring to early fall. 


Genus Ageniella Banks 


Clypeus of moderate size, the apical margin truncate, somewhat 
concave, or convex, often with a median blunt point; mentum of 
female with a few long, slender, weakly curved hairs; front tibia with- 
out one of the apical bristles specialized; dorsal edge of hind tibia 
smooth in the male, smooth or serrate in the female; last tarsal seg- 
ment with or without preapical bristles beneath; propodeum without, 
or sometimes with a few long erect hairs; first tergite without a line 
separating off the epipleuron; female without a pygidial area; sub- 
genital plate of male rather narrow. 

This genus is best developed in the Neotropics, with a considerable 
body of species occurring in the southern portion of the Nearctic 
Region. It seems not to occur in the Old World, unless the oriental 
Meragenia should be included as a subgenus. Ageniella leucippe Banks 
1941, described from the Solomon Islands, is a species of Auplopus 
(new combination). The species have considerable structural diver- 
sity and may be separated into natural groups, the more distinct of 
which are treated here as subgenera.

be no difference in the flight season of the sexes. A female from 
Baldwin, Kans. and another from Raleigh, N. C., were taken while 
transporting immature specimens of Agelenopsis sp. Both sexes have 
been taken in numbers at the nectaries of Cassia nictitans, and at 
Raleigh, N. C., both sexes were found frequenting a sunlit bare red-

176 U. S. NATIONAL MUSEUM BULLETIN 209 


SPECIMENS (2807, 459): From California (Calexico and Imperial 
County); ‘“Dakota”; Kansas (Dickinson County, Douglas County, 
and Manhattan); Louisiana (Tallulah); Missouri (St. Louis); Texas 
(Brazoria County, College Station, Dallas, Fort Davis, Lee County, 
Maxwell, McLennan County, Plano, Rio Grande River in Hidalgo 
County, Riviera Beach in Kleburg County, Victoria, Waco, and Wil- 
liamson County). 

The type of Priophanes otiosa is from Santa Cruz, Bolivia, and in 
the Cambridge Collection are two females from Blairmont, British 
Guiana, collected in Nov. 1928 by F. X. Williams; these indicate a 
wide distribution in the Neotropics. Dates of the collections are 
mostly from the middle of June to the middle of September. Early 
and late dates are: Apr. 30 in Brazos County, Texas; April and May 
in Imperial County, Calif.; May 30 in Lee County, Tex.; June 2 at 
Maxwell, Tex.; Sept. 10 and Oct. 10 in Riley County, Kans.; and 
Oct. 7 in Williamson County, Tex. There seems to be little difference 
in the flight period of the sexes. 

This species occurs in the warmer portions of the Central States, in 
southern California, and south to British Guiana and Bolivia. It has 
not yet been taken east of Louisiana or Missouri. Adults occur 
through the warmer part of the season. 


Subgenus Priophanes Banks 


Priophanes Banks, 1944, Psyche, vol. 50, p. 82. Type: Priocnemis facetus 
Cresson; original designation. 


Clypeus with its hairless apical margin rather wide, partially or 
entirely mat, and separated from the rest of the clypeus by a weak 
groove; mesopleuron without an oblique carina at the front end of its 
transverse suture; propodeum posteriorly with a few inconspicuous 
erect hairs; brush on innner side of hind tibia continuous to the apex; 
hind tibia of female with two external rows of teeth, a dorsal row of 
chevron-shaped teeth and a subdorsal row of subtuberculate teeth, the 
tibia not longitudinally concave between the two rows; sixth sternite 
of male with a median, apical, weakly raised, rounded ridge, the 
sternite impressed on each side of the ridge; subgenital plate of male 
short spatulate, with a median longitudinal raised area which tapers 
from a base of appreciable width to a narrow apex reaching or sur- 
passing the midpoint of the plate. 

All tibial spurs of male white, whitish, or stramineous, more or less 
fuscous at the base. 

This subgenus includes the eight Nearctic species treated below and 
the Neotropic Priocnemis dowi Banks 1938 (=Priocnemis arioles 
Banks 1944, new synonymy), Priocnemis parkeri Banks 1925, Prio- 


PEPSINAE: TRIBE MACROMERINI L7Z 


phanes comes Banks 1946, Priophanes pictipennis Banks 1946, and 
Priophanes rufigaster Banks 1946. The Neotropic species have not 
previously been referred to Ageniella and the first two listed have not 
previously been placed in Priophanes. Ameragenia adele Banks 1946 
probably belongs here, but the type lacks the abdomen and hind 
tibiae and so is difficult to classify. Bradley (1944, Notulae Naturae, 
No. 145, p. 6) places Pompilus (Priocnemis) sartorianus Cresson 1867 
in Priophanes. I have studied the type of sartorianus and though it is 
a member of the Macromerini with teeth on the outside of the hind 
tibia, it disagrees in several characters with Priophanes as defined 
here.

PEPSINAE: TRIBE MACROMERINI 183 


This is a subspecies of the Gulf and South Atlantic States, except 
Florida, where it is replaced by the subspecies ventralis. Seasonal 
data suggest an early summer and a late summer brood. The females 
from Takoma Park, Md., were taken in a damp meadow of grass 
and Solidago, at honeydew; those from Raleigh in September and 
October were taken at the nectaries of Cassia nictitans. All these 
looked and acted like large red ants crawling over the vegetation, 
and were rather slow to take flight, trusting more to their legs. 


3b. Ageniella (Priophanes) faceta ventralis, new subspecies 


Mats: Fulvo-ferruginous. Tibial spurs white, the middle and hind 
ones ferruginous basally; wings subhyaline, with a cloud over the basal 
vein, a broader cloud just beyond the stigma, and its apex infuscate; 
first abdominal segment and basal part of second abdominal segment 
fulvous, the rest of the abdomen blackish with a fulvous tinge at the 
apex.

This species has been taken only in California. Though super- 
ficially similar to A. arcuata or A. agenioides, according to whether 
the abdomen is red or black, respectively, it is distinct from both in 
several minor characters and has a different range. 


Subgenus Ageniella Banks 


Ageniella Banks, 1912, Journ. New York Ent. Soc., vol. 19, p. 222. Type: 
Pompilus (Agenia) acceptus Cresson; original designation. 

Hairless apical margin of clypeus usually polished and nearly 
always set off from the rest of the clypeus by a groove; mesopleuron 
with or without an oblique carina at the front end of its transverse 
groove; propodeum usually without any erect hairs, only with pubes- 
cence; brush on inner side of hind tibia with or without a subapical 
interruption; upper side of hind tibia without teeth; sixth sternite of 
male with a median apical, weakly raised, rounded ridge, on each 
side of which the sternite is impressed; subgenital plate of male 
usually tectate. 

Fore and middle tibial spurs whitish or blackish; hind tibial spurs 
blackish, or if the insect’s body is rufous the tibial spurs may all be 
ferruginous. 

This subgenus is well developed in the southern half of North 
America and in the West Indies. A few species reach southern 
Canada. Several are known from Panamé, but only one (the Chilean 
argenteosignatus) from farther south. The known species may be

records unusually early and late: May 23 at Valentine, Tex.; June 1 
at Washington, D. C.; Sept. 9 at Washington, D. C.; and Sept. 11 
at Reno, Nev. A male and a female have been collected on flowers 
of Asclepias, and the following four females were taken with prey: 
9, with immature Zelotus sp., Menlo Park, Calif., July 13, 1937, 
F. X. Williams; 29, both with females of Gnaphosa sericata, Washing-

Onaga, Kans., in Burlington County, N. J., and at Washington, D. C.; 
Sept. 6 at Falls Church, Va., Sept. 7 at Ridgeway, Ont., Sept. 8 at 
Aylmer, Que., and Sept. 23 at Cabin John (near Washington, D. C.), 
Md. Seven of the collected lots are definitely recorded from woods. 
Included in these is a collection of 11 &, 6 9 from ‘‘dense woods,” 
and a collection of 2 9 taken ‘“‘on bushes in open woods.” 

This is a woodland species of the Alleghenian and Carolinian faunas. 
There seems to be a single generation a year; it emerges late in July 
and is on the wing into early September.

Extensive seasonal data for Washington, D. C., record males on the 
wing from June 15 to Aug. 6 and females from June 18 to Oct. 5, with 
most of the females taken in July, August, and September. In 
warmer climates females have been taken a little earlier and later, as 
on May 38 at Fedor, Tex., May 18 to 21 at Spring Creek, Ga., May 21 
at Coachella, Calif., and Nov. 18 in St. Johns County, Fla. Three 
of the specimens have with them the prey they were carrying when 
captured: @, Washington, D. C., Sept. 6, 1946, M. Vogel, with an 
immature of Lycosa avara; 2, Washington, D. C., July 1945, M. 
Vogel, with an immature of Lycosa sp; and 9, Riverhead, N. Y., 
Aug. 1, 1917, Wm. T. Davis, with an immature of Lycosa sp. Vogel 
reports that he has taken this species a number of times with prey. 
In each case the legs had been taken off, but palpi were still present. 

This species is transcontinental, mostly in the Upper Austral Zone. 
Adults are commonest in July, August, and September. Immature 
specimens of Lycosa constitute the prey.

Utah (Bountiful); Virginia (Cape Charles); and México (Las Ruscias 
at Muzquiz in Coahuila). 

Adults seem to be on the wing throughout the warmer months. 
The earliest collection date is Apr. 10 at Brownsville, Tex., and the 
latest Oct. 24 at Victoria, Tex. Many specimens of both sexes taken 


PEPSINAE: TRIBE MACROMERINI 2N5 


at Raleigh, N. C., indicate that the period of greatest abundance 
there is July, August, and September. Both sexes have been taken 
commonly at nectaries of Cassia nictitans, and the species has been 
collected also on Euphorbia marginata, Baccharis glutinosa, and Bifora 
americana. The females seem to hunt primarily on ground with 
sparse, short vegetation such as on run-down lawns or abandoned 
eroded fields. They run over the ground with the abdomen tucked 
forward in a way that gives an appearance like that of Pogonomyrmez. 
There is also a resemblance to some female mutillids. When at 
nectaries among vegetation they crawl about with the abdomen in a 
normal position and look much like a large Formica pallide-fulva. 
Females are slow to take flight, which increases their antlike appear- 
ance. 

This species is transcontinental in the Lower Austral Zone. Adults 
are on the wing in the warmer months. 


Subgenus Ameragenia Banks 


Ameragenia Banks, 1945, Bol. Ent. Venezolana, vol. 4, p. 125. Type: Ameragenia 
trene Banks; monobasic. 

Hairless apical margin of clypeus not separated from the rest of 
the face by a groove, or sometimes separated by a groove; meso- 
pleuron without an oblique carina at the front end of its transverse 
groove; propodeum with many long erect hairs; brush on inner side 
of hind tibia continuous to the apex; spines on tibiae, especially in 
the female, numerous, stout, and divergent, in the female the hind 
tibia often somewhat tuberculate at the bases of the spines; forewing 
with the second cubital cell usually rather short and the third long, 
the third cubital cell receiving the second recurrent vein at about 
its basal 0.35 (in the other subgenera receiving the second recurrent 
vein near or beyond its middle); sixth sternite of male with a median 
apical, weakly raised, rounded ridge, on each side of which the sternite 
is impressed; subgenital plate narrowly tectate, variable. 

Coloration of tibial spurs of male variable.

Genus Priocnemella Banks 


Priocnemella Banks, 1925, Bull. Mus. Comp. Zool., vol. 67, p. 337. Type: 
Priocnemis (Priocnemella) fairchildi Banks; designated by Pate, 1946. 

Eragenia Banks, 1946, Bull. Mus. Comp. Zool., vol. 96, p. 421 (new synonymy). 
Type: Hragenia infelix Banks; original designation. 

Clypeus broad, short, with a troughlike impression paralleling its 
lateroapical margin, the apical margin broadly truncate in the female, 
in the male emarginate, truncate, or specialized; mentum of female 
with a sparse brush of long slender hairs with curved tips; apex of 
front tibia on the hind side with a spinelike bristle that is stronger 
than its neighbors and distinctly recurved (best developed in the 
female); dorsal edge of hind tibia almost or quite smooth; under side 
of last tarsal segment without distinct preapical bristles; propodeum 
without long erect hairs; first tergite without a line separating the 
epipleuron; female without a pygidial area. 

This is a compact genus of Neotropic species, one of which reaches 
southern Texas. Besides this one, the species of which I have seen 
the types are Ageniella isolata Banks, 1925, A. rufothoraz Banks 1925, 
A. bequaerti Banks 1945, A. caloptera Banks 1945, A. delila Banks 
1944, A. amoena Banks 1946, Priocnemis fairchildi Banks 1925, 
Eragenia infelix Banks 1946, and Lissagenia insignis Banks 1946. 
Except for fairchildi, these are all new combinations in Priocnemella.

in the type of rufula and in the specimen from Ecuador; wrinkling as 
transverse parallel ridges in the specimen from Panam4é; and wrinkling 
as a faint, fine, irregular reticulation in the specimen from Texas. 
These three types of wrinkling suggest that there are three species 
involved, but more specimens are needed to solve this question. 

Fulvous. Prosternum and median areas on mesosternum and 
metasternum fuscous; wings lightly suffused with yellowish brown, 
the forewing with narrow transverse brown bands along the basal 
vein and nervulus, just beyond the stigma, and at the apex. These 
bands are a little narrower in the male and in the female from Panama 
than in the other specimens. 

The name tabascoensis is applied according to Cameron’s original 
description and figure and notes on the type supplied by Mr. I. 
Yarrow. More specimens may show that more than one species is 
included here.

Subfamily CEROPALINAE 


Probably the sharply compressed subgenital plate of the female is 
the most distinctive recognition mark of the subfamily Ceropalinae, 
the characters of which are summarized in the key. Most of these 


CEROPALINAE: TRIBE NOTOCYPHINI 221 


characters indicate it a derivative of the same stock as the Psammo- 
charinae and it may well be a polyphyletic offshoot of that group. 
Probably many years will elapse before it can be shown with satis- 
faction whether the present limits of the subfamily Ceropalinae is a 
natural one. The genera included in it here agree in certain mor- 
phological characters and have a biological similarity in that they do 
not store spiders in nests. The Notocyphini and Minageniini, as far 
as known, oviposit on spiders which continue to be free and active 
until the growing wasp larva finally kills it. A few Psammocharinae 
(e. g., Homonotus) have somewhat similar habits. The Ceropalini 
oviposit on the spider prey of other psammocharids and thus live as 
social parasites. Grouping these three tribes together as a single 
subfamily emphasizes these similarities and avoids the maintenance 
of a large number of small subfamilies. It is hoped that this arrange- 
ment may prove a useful one. 


Key to the tribes of Ceropalinae

Tribe Notocyphini 


Labrum large and exposed; eyes subparallel within; flagellum flex- 
ible and not unusually thickened; thorax long; propodeum long, at 
least in the female with a long dorsal face and a well differentiated 
posterior face; stigma small, about 2.5 as long as wide; nervellus ending 
at or distad of the juncture of cubitella with discoidella; middle and 
hind femora often with spinelike bristles set in pits; spinelike bristles 
on outer apical margin of hind tibia short, regular, closely spaced, 
and usually forming an uninterrupted row; last segment of tarsi often 
with a median ventral row of bristles; female subgenital plate com- 
pressed, with a median, ventral longitudinal ridge, at least apically; 
sting decurved. 

There are two genera known, the Oriental Minotocyphus(=Sinoto- 
cyphus, new synonymy), and the predominately Neotropic Notocyphus. 
They differ most conspicuously in the shape of the apical margin of 
the labrum, convexly rounded in Minotocyphus and concavely emar- 
ginate in Notocyphus.

Genus Notocyphus Smith 


Notocyphus Smith, 1855. Catalogue of the hymenopterous insects in the... 
British Museum, pt. 3, p. 172. Type: Notocyphus saevissimus Smith; 
designated by Smith, 1873. 


This is a genus of the Neotropics, with a single polytypic species 
invading the southwestern portion of the United States. In 1951 
(U.S. Dep. Agr., Agr. Monogr. No. 2, p. 920) I considered this species 
identical with the Mexican Notocyphus plagiatus Smith, but notes on 
the type of plagiatus sent to me from the British Museum by 
Mr. I. Yarrow indicate that it is probably distinct.

Genus, Minagenia Banks 


Minagenia Banks, 1934, Proc. Amer. Acad. Arts. Sci., vol. 69, pp. 40, 64. Type: 
Pseudagenia (Minagenia) brevicornis Banks; original designation. 

Nannochilus Banks, 1944, Bull. Mus. Comp. Zool., vol. 94, p. 171. Type: Pseuda- 
genia externa Banks; original designation. 

Minagenia probably has a wide distribution, but seems to be rare 
outside of the Western Hemisphere. Besides the genotype from the 
Philippines, I have seen a paratype of the Madagascan Micragenia 
minima Banks 1941, which is referable to*Minagenia (new combi- 
nation). The Neotropic species of which I have seen the types are 
Pompilus levipes Cresson 1869, Nannochilus obscurus Banks 1946, 
N. peruanus Banks 1946, N. laevis Banks 1946, and Minagenia minor 
Dreisbach 1953 (all but MZ. minor are new combinations in Minagenia). 

The Neartic species have a close structural similarity and a variable 
coloration. They are best distinguished by the male genitalia. These 
structures, however, are variable within a species, so that a series is 
needed for understanding the basic specific patterns. ‘The females 
belonging with the males have been identified with certainty in some 
cases, in other cases with doubt or not at all. In the treatment 
below females are included only in those cases where correlations 
with the males are certain or probable. 

What little is known about the biology of Minagenia indicates 
that the larva lives as an external parasite on the abdomen of an 
active spider, somewhat like the polysphinctine ichneumonids. The 
cocoon apparently is spun under bark or in similar places, probably 
wherever the spider succumbs.

This female was collected in several localities with the male clypeata, 
but also in some areas with the male osoria._ It seems more likely that 
it belongs with clypeata, but there is a possibility that the association 
is mistaken or that the females of both species are confused in the 
series.

Tribe Ceropalini 


Labrum large, conspicuously exposed; eyes divergent dorsally, 
their inner margins concave above; flagellum rather inflexible and 
thickened; thorax rather short, the propodeum short and rather flat 
in profile; stigma about 4.0 as long as wide; nervellus ending dis- 
tinctly basad of the juncture of cubitella with discoidella (pl. 1, fig. 14) ; 
middle and hind femora often with a few spinelike bristles set in pits; 
spinelike bristles on outer apical margin of hind tibia moderately 
weak, somewhat irregular in length, forming an irregular or inter- 
rupted row; last segment of tarsi often with preapical spinelike 
bristles that are arranged in two irregular, ventral, sublateral rows; 
female subgenital plate strongly compressed, in side view somewhat 
produced apically, with a brief median ventral longitudinal ridge at 
the apex; sting straight, strong. 

Three genera are known: the Oriental Xanthampulex, the Neo-

tropic Irenangelus, and the worldwide Ceropales. A number of 
features distinguish Ceropales from the other Holarctic Psammo- 
charidae, and for this reason there has been a tendency to differentiate 
this genus sharply from the rest of the family, sometimes even to con- 
sider it as a separate family. However, it seems certain that Xan- 
thampulex and Irenangelus are very close to Ceropales, and if the 
characters of this natural group of genera is considered, rather than of 
Ceropales alone, there seems less justification for the traditional 
separation. The widespread opinion that the male genitalia of 
Ceropales are distinctive enough to justify family rank shows lack of 
familiarity with the range of variation of these structures within 
Ceropales and of the conditions in Xanthampulex and Irenangelus. 

The members of the Ceropalini are social parasites on other psam- 
mocharids. The female parasite oviposits into a book lung of the 
spider prey of the host, while it is left unguarded for a moment some 
time after capture. After the spider is placed in a nest by the host, 
the ceropaline egg hatches, and the resulting larva consumes the host 
egg and then the spider. The female parasites have sometimes been 
seen trailing females of prospective hosts, to be on hand when a spider 
is captured. 

Genus Ceropales Latreille

This is the only genus of the Ceropalini occurring in the Nearctic 
region. It may be distinguished from nearly all other psammo- 
charid genera by the fact that the hind tarsal claws are bent at the 
middle in a sharp right angle. 

The Western Hemisphere species of Ceropales divide easily into 
four species groups as indicated in the keys and descriptions below. 
Very few Eastern Hemisphere species have been available for study 
but it seems that most of them belong in groups different from those 
defined for our fauna.

Colored like the subspecies fraterna, except that the legs beyond 
the trochanters are mostly rufous, the femora being rather clear 
rufous with the base fuscous and the apex usually with a yellow spot. 

The hind femur on the front side is mostly clear rufous, while in 
the subspecies fraterna it is mostly brown to blackish. Intergrades 
between the two forms are common, but are assigned to one subspecies 
or the other according to the clearness and extent of the rufous color 
on the front side of the hind femur. A distinct fuscous or brownish 
tinge or extensive infuscation places the specimen in the subspecies 
fraterna.

of legs grading from black basally to fulvous apically, the hind femur 
blackish to light brown with the apex usually paler than the base 
(also with a yellowish spot on the apex). 


CEROPALINAE: TRIBE CEROPALINI 245 


This subspecies is the most widespread one in North America. It 
differs from the subspecies caenosa in having a yellow apical band 
on the third tergite, from rhodomerus in having the hind femur blackish 
or brown rather than rufous, and from stretchi2 in the less extensive 
yellow markings, having less than the apical third of the hind femur 
marked with yellow, usually a median black stripe on the face and 
clypeus of the female, and narrower yellow bands on the abdomen. 
Intergrades and mixed populations with the other subspecies are 
common.

The great majority of collection dates are in July, August, and the 
first half of September, though others indicate that the species may 
be less frequently collected from late spring to late in September and 
rarely earlier or later. Some unusually early and late dates of interest 
are: Apr. 12 at Kings Mt., San Mateo County, Calif.; April at 
Baldwin, Kans.; May 1 at Raleigh, N. C.; May 15 at Verona, N. Dak.;

Forest Grove, Oreg.; Sept. 30 at Ulkiah, Calif.; Oct. 3 at Ann Arbor, 
Mich.; Oct. 10 at Linglestown, Pa.; Oct. 13 at Jordan, Ont.; and 
Oct. 24 at Antioch, Calif. Flower records include Ranunculus cali-

spinosa, Lomatium sp., Pastinaca sativa, Daucus carota (5 collections), 
Aster sp., and Solidago spp. (8 collections). One collection is from 
honeydew of Cirsium lanceolatum. In my own collecting experience 
the species is rather common on flowers, and may be found on shrubby 
undergrowth around the edges of or in clearings in woods. 

This subspecies is transcontinental, primarily in the Canadian and 
Transition Zones. In the far West it is largely replaced by the 
subspecies stretchit and caenosa, and in the Alberta to Dakotas area 
by the subspecies rhodomerus. Adults are on the wing mostly from 
July 1 to Sept. 15. 


le. Ceropales maculata stretchii Fox 


Ceropales stretchii Fox, 1892, Trans. Amer. Ent. Soc., vol. 19, p. 52,9. Lectotype: 
92, California (Philadelphia). 

Black. Yellow and rufous markings similar to those of the sub- 
species fraterna, but the yellow marks more extensive (and never 
whitish as is frequently the case in fraterna). The face, clypeus, and 
labrum of the female never have a median black stripe, the yellow 
on the front side of the hind femur occupies from the apical third 
to most of its length, and the yellow bands on the abdomen are 
very wide. The yellow on the hind femur may be broken basally 
into small blotches, yet if these reach basad one third the length 
of the femur the specimen should be referred to the present sub- 
species. The first tergite is yellow for about 0.4 its length in the male 
and 0.6 its length in the female, the two lateral yellow spots of the 
male being approximate on the midline or fused into a continuous 
transverse band. 

Intergrades with the subspecies fraterna are the rule where the ranges 
of the two overlap. Females of stretchii are more strongly differenti- 
ated from those of fraterna than are males, and in many localities 
where most of the females may be referred to stretchii, most of the 
males are indistinguishable from fraterna.

Ficure 144.—Localities for Ceropales maculata stretchit. 


This subspecies occurs most typically throughout California east 
of the crest of the Sierra Nevada, though in northern California and 
in the Coast Range specimens of the subspecies fraterna and inter- 
grades are common. It extends northward with more pronounced 
dilution with fraterna into British Columbia and westward to Idaho 
and northern Nevada and Utah. Adults are commonest during the 
summer and early fall. 


ROBINSONIIT GROUP 


Forewing 5.5 to 16 mm. long; body of medium build; antenna of 
moderate length; hind legs long; longer hairs of frons suberect, rather 
short and sparse; longer hairs on mesoscutum short, inconspicuous; 
second to fourth segments of fore and middle tarsi of male not unusu- 
ally short, the second segment of the middle tarsus distinctly longer 
than wide; hind tarsus unusually long; last segment of fore tarsus of 
male with a strong median thumblike lobe on the front side; claws on 
fore and middle tarsi of male with a large, appressed, obliquely trun- 
cate tooth, the tooth postmedian on the claws of the middle tarsus and 
on the hind claw of the front tarsus, shorter, more pointed, and sub- 


CEROPALINAE: TRIBE CEROPALINI 249 


basal on the front claw of the front tarsus; claws on fore and middle 
tarsi of female with a large, appressed, obliquely truncate, postmedian 
tooth; male subgenital plate broad, semicircular or subtriangular, its 
apex rounded or emarginate, its edges turned down, often thickened; 
female subgenital plate in profile with a projecting apical part whose 
apex is evenly rounded; male cerci in the form of semicircular or short 
triangular flaps that usually protrude beyond the seventh tergite. 

This group contains two subgroups: 1. The bipunciata subgroup 
comprising large species with the male subgenital plate rounded at the 
apex, the head rather broad, and the finer punctures on the thorax 
small and very dense. The Nearctic elegans, nigripes, and bipunctata 
areincluded. 2. The rebinsoni subgroup comprising usually medium 
sized species with the male subgenital plate more or less pointed at the 
apex, head slightly narrower, and the thoracic punctation variable. 
The propodeum is usually somewhat swollen basally, the basal swelling 
divided medially by an impression or broad groove. The Nearctic 
robinsonit, cubensis, and longipes and a host of Neotropic species belong 
here. Some Nearctic representatives of the fulvipes and femoralis 
groups are common in México or range even to Panamé, but all the 
strictly Neotropic species of Ceropales I have seen belong to the present 
subgroup. 


2. Ceropales cubensis Cresson 


Forewing of male 5 to 8 mm. long, of female 6.5 to 9 mm. long; 
irons, mesoscutum, and mesopleuron with dense small punctures and 
scattered large punctures, the latter averaging a little smaller than in 
the related species longipes; propodeum tumid basally, the basal 
swelling divided medially by a longitudinal groove that is broadened 
basally into an impressed triangular area; apical half of propodeum 
a little concave medially, but convex next to the attachment of the 
abdomen; median apical portion of propodeum with rather dense fine 
punctures that are stronger and somewhat irregular medially; male 
subgenital plate broadly lanceolate with a blunt tip. The details of 
the subgenital plate are specifically diagnostic. 

Black. Face (except small area below antennal tubercle of female), 
clypeus (except a small median area in the female), side 0.25 of frons, 
antennal tubercle, narrow postorbital stripe, labrum (except central 
part in the female), scape except above (or only below in the female), 
underside of pedicel, underside of base of first flagellar segment in the 
male, sometimes a spot on outer base of mandible, anterior callus and 
hind margin of pronotum, rarely a smal] median spot on mesoscutum, 
small central spot on scutellum, postscutellum, hind corner of thorax, 
underside of front coxa, apical outer marks on middle and hind coxa, 
usually the apical margins of the trochanters, front tibia and basi- 
tarsus of male dorsally, middle basitarsus of male except at the apex, 


250 U. S. NATIONAL MUSEUM BULLETIN 209 


apical marks on front and middle femora of male (these marks some- 
times present but small in the female), sometimes a small spot on outer 
apex of hind femur of male, apical blotches or bands on fore and mid- 
dle tibiae (large in the male, reduced in the female), and certain abdom- 
inal markings, pale yellow or ivory. The abdominal markings of the 
female vary with the subspecies and are described under the subspecific 
headings; those of the male are as follows: a large, sublateral, subapical, 
quadrate spot on the frst tergite, subapical transverse bands on second 
to fifth tergites (deeply notched sublaterally), a large median and a 
somewhat smaller sublateral spot on sixth tergite (these sometimes 
narrowly joined along the hind margin), and a large subcircular median 
spot on seventh tergite, pale yellow or ivory; wings subhyaline; palpi 
pale brown; legs fulvous, the coxae and trochanters often more or less 
fuscous; hind tarsus and apices of tibiae sometimes infuscate; male 
subgenital plate with a broad whitish margin, within which is a 
blackish border extending to the median basal triangular piece, which is 
whitish with a blackish triangular center. 

There are two subspecies, one in the West Indies and one from 
Panama to southern Texas. They differ in the sharpness of the small 
punctures on the head and thorax and in the color of the female 
abdomen. Their male genitalia are identical. 


2a. Ceropales cubensis albopicia Cresson, new status 


Ceropales albopicta Cresson, 1869, Proc. Boston Soc. Nat. Hist., vol. 12, p. 378, 
“o”—=¢, Lectotype: o, Orizaba, México (Philadelphia). 

Smaller punctures on frons, mesoscutum, and mesopleuron rather 
weak and often not well defined. 

Hind tibia and tarsus rufous, the tarsus often somewhat infuscate; 
abdomen of female rufous, the first tergite more or less infuscate 
basally, usually with a small subapical dorsolateral ivory colored spot, 
and the abdominal tergites with additional ivory subapical marks as 
follows: irregular sublateral transverse marks on the second tergite, 
similar but medially approximate marks on the third tergite (these are 
often broken into a median and a sublateral pair of marks), a large 
median and smaller sublateral transverse marks on the fourth tergite, 
a large median semicircular mark on the fifth tergite, and a large 
median subcircular spot covering the median part of the sixth tergite. 

This is the form identified by Fox (1892, Trans. Amer. Ent. Soc., 
vol. 19, p. 56) as Ceropales agilis Smith, 1864. Mr. I. Yarrow has 
compared specimens with the type of agilis in London and finds that 
agilis is a distinct species, with some colorational differences, and large 
coarse punctures on the frons and clypeus.

This is very close to C. bipunctata and has allopatric distribution. It 
is rated as a full species rather than as a subspecies of bipunctata be- 
cause there are several distinctive color differences, the male genitalia 
are slightly different, and no intergrading specimens are at hand.

Va.; Oct. 11 at Castle Rock, Pa.; and Oct. 17 at Raleigh, N. C. The 
seasonal data indicates a single annual generation over most of the 
range, and two in Texas. Flower records comprise Ampelopsis arborea 
(three collections), Euphorbia marginata, Stillingia sylvatica, Poly- 
taenia nuttallii, Aster paniculatus, and Solidago spp. (five collections). 

This subspecies occurs in the Alleghenian and Carolinian faunas. 
Adults fly mostly in August and September. They are commonly 
collected on Solidago flowers. 


FEMORALIS GROUP 


Forewing 2.5 to 5.7 mm. long; head large; abdomen small; antenna 
short and stout; femora rather stout and flattened; longer hairs of 
frons reclined, long, and conspicuous; longer hairs on mesoscutum 
long and conspicuous; second to fourth segments of fore and middle 
tarsi of male not unusually short, the second segment of the middle 
tarsus distinctly longer than wide; last segment of fore tarsus of male 
with a subapical swelling on the front side; claws on fore and middle 
tarsi of male with a large, appressed, obliquely truncate tooth, the 
tooth postmedian on the claws of the middle tarsus and on the hind 
claw of the front tarsus, and shorter, more pointed, and subbasal on 
the front claw of the front tarsus; claws on fore and middle tarsi of 
female with a large, appressed, obliquely truncate, postmedian tooth; 
male subgenital plate small, elongate with a rounded apex, the lateral 
edges turned up; female subgenital plate in profile rather triangular 
with a pointed apex, sometimes with only a suggestion of a projecting 
apical part; seventh tergite of male very convex and enclosing the 
terminalia and cerci. 

This group includes the Nearctic femoralis, hatoda, rugata, and 
pacifica, and the Mexican C. mericana Cresson, 1869. The species 
femoralis occurs south to Panamaé. The size, color, and structure of 
these five are so uniform that without close observation all might 
pass as a single species.

smaller (or some of the smaller ones lacking entirely), that the longer 
hairs of the head and thorax are dark brown, and that the front and 
middle femora and tibiae are more or less infuscate.

The type of Ceropales brevicornis is lost. Fox (1892, Trans. Amer. 
Ent. Soc., vol. 19, p. 58) reports having seen it but does not clarify its 
specific identity. The original description fits both the present 
species and C. fulvipes. Since the type locality (northwestern Kansas) 
is out of the known range of C. fulvipes and well within that of the 
present species, the name is applied here. 

SPECIMENS (330', 24 9): From Alberta (Manyberries); District of 
Columbia (Washington); Illinois (“‘N. IIl.’’); Indiana (vicinity of 
Indianapolis) ; Iowa (Ames and Sioux City); Kansas (Baldwin, Clay 
County, Dickinson County, Edwards County, Riley County, and 
Topeka); Louisiana (Tallulah); Minnesota (Fort Snelling, Luverne, 
Norman County, Winnebago, and Yellow Medicine County); Mon- 
tana; Nebraska (Bartley); New Mexico (Las Vegas); North Dakota 
(Beach); Pennsylvania (Arendtsville and Newtown); South Dakota 
(Cedar Pass and Phillip) ; Texas; Virginia (Falls Church) ; and ‘‘Wash- 
ington Territory” (‘‘Taylors, Wenass V.”’). 

Collection dates are from June 18 to Oct. 7, the earlier and later 
captures being: June 18 at Ames, Iowa; June 26 at Arendtsville, Pa.; 
June in Riley County, Kans.; Sept. 15 in Yellow Medicine County, 
Minn.; Sept. 17 in Riley County, Kans., and at Sioux City, Iowa; 
and Oct. 7 at Baldwin, Kans. Flower records include Asclepias pumila 
and Solidago sp. 

This is a widely distributed but uncommon species known from 
Louisiana, Texas, and New Mexico north to Pennsylvania and 
Alberta. There is a single record from west of the Rocky Mountains, 
from ‘‘Taylors, Wenass V., Washington Territory, VII-6-82.”
